im new to the game, is tank necessary for the team?
because im planning to replace my Leon(my 1 and only tank right now) with my vincent(still 4*going to make him zerk)
my current line-up is
4* lucille-priest
5* ronan-MW (first hero to promote to 5)
5* kai-ninja (got from draw)
4* cybella-marksman
4* leon-zealot
bench hero
4* vincent
4* luthor-sage
3* kahuna
another question is about runes.
should i wait and collect 1slot 2*-5runes? or use any runes that can fit?
THANKS IN ADVANCE FOR YOUR HELP
