na this is why its good
you see, people tend to play OP classes, warrior is a good example
4 out of 5 your screenshots has warriors stacked
what do you get when you have class stacking in a team?
well generaly it becomes weaker, cuz it descreases amount of cc, mixed dmg, etc your teams gets, and gameplay gets pretty onesided
so what class stacking does with this excessive warrior population? exactly: it lower its power - by playing op class you get a chance your team will be stacked
apparently class stacking is a good balancing tool, which increases chances of weak and unpopular classes to succeed. yeah, it can hurt healer/dps comb, like in ww\mw setup, nut this will also increase class baance
dont forget about more fun, this is SOLOQ, not ass-serious 3v3, and how you will see 1 warr in every team if class stacking will be disabled
if we disable it, we better call it "war-x-x soloq"
