It isn't free for main... main wastes 20% Xp to be respeceed....
There isn't such thing as a main character anymore Pepe, and it's like that for more than 2 years already.
This patch just finally removed such things as "alts" or "main" completely. You can change your strat hero at anytime, you can respec one character for free once a week, you can send looms around on any character, you can be in dozens of clans at the same time with different characters or even just put the very same chracter in different clans if you wish, just have to make a few clicks.
Yeah, there is the strat hero limitation, and thats it.
I just can't believe people still QQ about certain playstyles/builds or whatever if they just could insta respec into that class/build without any penalty at all, or into a counter class, or into fucking whatever they're in the mood to.
