Why is everyone acting like Wendy's god tier all of a sudden, she isn't Natsu and sadly Wendy is still by far the weakest Dragon Slayer. I don't think Wendy could defeat Eric, Sting or Rouge in a one on one fight.
As for Lucy she has shown time and time again that she's a very versatile fighter. If it wasn't for her quick thinking most of the guild would of been dead in the Jacob fight. Mavis who's suppose to be the
Fairy Tactician couldn't even come up with a plan to counter Jacob's magic but Lucy's quick thinking saved the day and she stole the show in that fight.
Lucy's Stardress also has fixed many of her shortcomings and has added to her arsenal of techniques.
Taurus Form: increases her strength which should in turn also increase her durability. Lucy could of easily used Earth Wave in the Jacob fight but she would of destroyed the guild, so Jacob's fight shouldn't be a benchmark for Lucy's power for the simple fact that both her and Natsu were both holding back inside of a building that they both hold very dear to them.

Leo Form: Also increases her strength but not at the same level as Taurus form. While not as strong it makes up for it by giving Lucy access to Regulus's light magic. I'm pretty sure Lucy could pull off an Regulus Impact and if She can't her boy Loke is fighting along side her in this form.
Virgo Form: Lucy hasn't shown off all she can do in this form but she has access to Virgo's Earth Dive magic allowing her to escape attacks and set up Earth traps. Not everything is flashy flashy boom in a battle, strategy is key too and Lucy's underground speed should be on par with Virgo. Plus we have let to see anything new from Vigro's Spica magic.

Spica Lock (anime only, over look if you like)

Sagittarius Form: One of my favorites which increases accuracy, if anyone has forgotten Sagittarius could counter gun bullets with his speed and accuracy with his normal arrows. Lucy's Star Shot is able to fire multiple homing light arrows at moving targets like she did Ajeel's flying sand. These arrows explode on impact.

Gemini Form: This one could counter Wendy for those who want to talk Vs fights. As you all already know Gemini is able to copy all skills and abilities of an Mage of similar magic power to Lucy. Let's say for argumentative purposes Base Wendy= Base Lucy in magic power. Gemini could copy Wendy easily. Now let's say Wendy step it up a notch and went DF. Gemini Stardress Form allows Lucy and Gemini to increase their magical power allowing them to copy greater foes but not foes who are Spriggan 12 level. This should allow Gemini to be able to copy DF Wendy and lets not forget Lucy's fights are never 1 on 1 but 2 on 1, or 3 on 1. Wendy can't fight herself and another opponent at the same time.
Aries Form: abilities are unknown, but Aries is a defensive fighter who can weaken oppoents, Lucy's Stardress should be based on this.
Scorpio Form: abilities unknown but Scorpio uses Sand Toradoes
Capricorn Form: abilities unknown...... Capricorn hasn't really shown off any magical abilities, could be Marital Art based
Cancer Form: abilites unknown but Cancer has amazing dexterous and speed, Hiro could incorporate this more in battles.
Aquarius Form: (lost for now) Lucy's water barrier was shown to block Jackal's explosions with easy allowing her to use Urano Metria.
Lucy has let to show off 4 of her other Stardresses and hasn't shown the full power of her other 5. Plus the possibilities of her getting back Aquarius are high and the possibility of getting the final two keys are there as well.
Hiro Mashima knows we all want to see a
Spirit Queen Stardress
So Lucy will be a power house in future fights, just look at who her Mother and Ancestor are, two powerful women who could open the Eclipse Gate something that took alot of magical power from multiple Mages (100s) in the GMG.
Sadly Lucy's full potential eclipses Wendy's (pun intended)
Everyone is looking at Wendy as if she's a little Natsu but they fail to realize Wendy will never be as strong as Natsu for one simple fact.... Natsu is a Demon who learnt DS magic, Wendy is a little girl who learnt DS magic. Natsu's potential is far to high for Wendy to catch up.
Wendy right now could possibly reach Sting and Rouge's level or she may in fact could already be close to their level of power because of Dragon Force. Wendy's Final benchmark of power has already been shown to us through Chelia.
Chelia and Wendy were always equals so Wendy's full potential should be equal to Chelia's 3rd origin but this is like full grown Wendy late 20s early 30s.
While Chelia was powerful she still needed Wendy's barrier to defeat Dimaria. I couldn't see someone like 3rd origin Chelia taking out the Spirit King so I doubt Wendy ever could.
Wendy has had her Spriggan fight and has a broken leg because of it, while Lucy on the other hand is still in fighting condition so we'll see what Lucy can do in the up coming chapters, and besides Hiro Mashima always gives Lucy a powerup mid fight
