Not asking for removal of rage cost... kinda...
Issue. I think what really bothers me about onslaught costing rage is that it is a bit annoying that I can't just use it when I start a fight if I have no rage. As for the rage cost itself, I guess I have no issue with onslaught costing rage, especially in ShB since we can just save 1 charge of infuriate for emergencies when we need onslaught but haven't the rage for it.
I get that onslaught needs a rage cost. I read the balance guide on wars, and I get that onslaught needs a rage cost because it helps with gauge management and GCD manipulation.
Suggestion.So how about wars be given the following trait:
Staying out of combat for 30 seconds gives the warrior XXXX buff which removes the beast gauge cost from the next onslaught. XXXX persists after logging out and logging back in.
This way, Wars can use onslaught immediately when starting fights if they want to, but it doesn't screw with GCD manipulation and gauge management after the fight has begun. After they're in combat even once, Wars just need to remember to save some gauge or use infuriate to end with some gauge if they wanna onslaught in between pulling packs of monsters or whatever. It's just a QOL fix which makes onslaught easier and more fun to use. This doesn't really mess with balance so none of the other tanks should be upset since onslaught retains the cost once in combat.
I get that it's not a big deal to most people. But it is to me. I love warriors and pretty much everything about the job I find fun. But this is an annoyance to me which I understand that perhaps many people couldn't care less about. But I'm sure there are some warriors out there that'd appreciate this little QOL change. I think this is a fair suggestion which balances the level of enjoyment and fun of an ability that all tanks share, but doesn't impact performance balance as it pertains to raids or progression or whatnot. I hope there's some support for this minor QOL change out there.
