This is my first time to create a blog.
Well here it goes.
During the Oracion Seis arc, Wizard Saint Jura Neekis is involved during the fray but he isn't stronger then compared today.
During Grimoire Heart Invasion (Tenrou Arc) it takes the likes of Makarov, Laxus and Gildarts and all FT just to defeat Grimoire Heart.
Now During Tartarus arc, it takes all FT members (with the exception of Gildarts) plus Crime Sorciere (Jellal and Meredy) and Sabertooth (Sting and Rogue; maybe in the future Orga, Rufus and Yukino would join the fray, also hoping the Aguria sisters (Angel and Yukino respecitively) to fight together if Angel would accept his alliance with CS along with his co-Oracion Seis members which most likely they'll accept, they are all wiped by Jellal alone, poor Oracion Seis sob...) to battle Tartarus.
I think Gildarts should comeback to even the playing field against Tartarus.
Hoping for a FT + CS + SBT + LS vs Tartarus
Also looking forward for the Team Natsu Slayers (Gray and Natsu) against E.N.D himself.
