Irrefutable issues on Warlock that need to be addressed.
Phoenix dive cool down.
Day break super having no justification for being used in PVP or PVE.
Vortex nova still remaining unused in PVP and PVE.
Chaos reach PVE damage being nothing compared to other class'
So many redundant exotics or too niche to ever see use. (cue someone commenting about some obscure build with a no hoper exotic that makes it "The strongest thing in the game that's absolutely broken"
Chaos Reach actually has one of the highest DPS figures - it's one downside is that it takes too long, while others you launched and do damage with a weapon while the super takes affect.
While you are entitled to your opinion, the viability of a super is more on the user's ability to apply it, then it's subjectively perceived value.
