Everyone, chill a bit...
While I am the first that only follow some advice (I like to make teams with more defense and healing that most), and agree that you do not need to be the absolutely best to have fun with the game, I agree with Slashley on the importance of 100% Eidolons. It is not to "be the very best and all content be easy". The ones who most benefit of an advantage like that are precisely the new players, who can scale on power more easily, and everyone on those contents where you struggle to win. I have no 100% Eidolon , and only a few friends with them (my friend list is not so good as I would like), but when I use those Eidolons on difficult content the difference is clear; today I have done two times accessory of lightning T4. The time I could chose an 100% Eidolon from a friend was perfect and smoothly. The other time, that handicap and some enemy triple attack made that combat an extremely difficult one. Is there, when you have problems, when you need them the most.
And more important, when you talk with people new to the game, talk about that kind of things is very important. One or two sentence like "but if you have some 100% Eidolon, you have a great advantage" and I do not think others while have a problem with the text.
See you all on play.
