I read somewhere that gear only matters in Dominion Mode. I don know if this is true or not so I thought I'd ask. Does gear matter outside of Dominion? Duel? Brawl? Deathmatch?
No. AFAIK gear only has any effect in Dominion and custom matches.
Gear does not affect the Duel and Brawl game modes.
Hmm, good to know. So I guess two players using the same hero would be identical in strengths and weaknesses?
