I'm sorry, but is Warrior completely broken in Crystal Conflict right now?

The only way I can reach Diamond is to become a WAR and pray that enemy team don't have a WAR, ezpz Diamond

Actually it's more like pray your team makes the best of your kit because if you have a team looking for sightseeings on the battlefield or seem to wait for a hunt train while you're solo'ing the enemy team for a minute straight on the aetherite chances are you lose. Because apparently they think it's a smart move to go in one by one to get killed. That being said WAR can't do jack on it's own outside of LB without a team to follow through, with a good team on the other hand you completely wreck.

This. I have now had many matches where I played WAR, my party stuck with me, and we just melted things in front of us.

I have also had more matches where I played WAR, half my team decided to go sightseeing in Narnia while chasing one bard, and I was left alone on the crystal to fight a futile battle of "Well, I can be really annoying to the enemy team for a surprisingly long time and force the crystal to a standstill, but eventually I run out of things to use to keep myself alive."

Dueling a WAR one-on-one can go badly. Dueling a WAR who has others at their side who will utilize their kit with the opening the WAR makes for them is likely to be a losing prospect. Dueling a WAR left alone four-on-one is all but a foregone conclusion... and it isn't in favor of the WAR. (The only way I've recovered in a scenario like that is a very carefully timed LB to negate Guard just before the turbulence, smack Guard myself to not get bounced, and wait for them to land. With diminished health, stun them all and try to finish them off. Sometimes it works. "Sometimes" is not, however, "always". Especially since that tactic really only works particularly effectively on the one map.)
