I've done it a few times, switching my main in World of Warcraft.
In Overwatch competitive season 12, most players play only one hero across all skill ratings, while the players that flex from support, damage, and tank roles are in the minority, according to the latest report from the OmnicMeta.
I've played a druid since WoW launched in 2004.
While talking during the leveling stream this week, we were discussing our plans for Legion launch day and Mitch said he was planning to go full 'gremlin D.Va' and just play until he was level 110.
As World of Warcraft has evolved, I've gone through a lot of "mains." My first class to level 60, which I raided with throughout vanilla, was a Warlock.
I've been loyal to my Druid main since World of Warcraft launched in 2004.
I feel that with tri- and quad- spec coming, the days of considering yourself an Arms Warrior or a Fury Warrior or a Protection Warrior (using Warriors as examples; fill in your own specs here) may be coming to an end.
If you're like me (you're almost certainly smart enough to not be like me) you've stuck with the same class for a while.
