Let’s start by doing something to the utterly ridiculous mobility of DHs and Monks because this is where it started back in MoP. They can pretty much ignore any snares you put on them and have more mobility spells than any 2 other specs put together. In PvP you cannot stop them from hitting you or running away, and in PvE the “move outta fire” mechanics don’t present them with any serious difficulty. Not like melee guys in general have to move, but when they do, they don’t lose output provided they keep in melee range. So the “move yesterday” parts get cranked up, because it’s too easy, and then casters have to move MORE despite already losing more output when moving while the hypermobile monkeys on speed still aren’t challenged, thus setting the new standard of mobility being DH/BM and it’s not that they are fast, but it’s everyone else that is slow.
THEN we can talk about casters having all DPS crammed in the designated “spender” or “proc” abilities. Which in general is cancer design.
It’s particularly visible in Elemental, where not only both spenders and the “proc” spell are instant, but they ALSO hit like 5x harder than 1,8s casts. Guess the Diablo devs couldn’t figure out how to make players use their lovechild instead of their baselike kit so they went all out.
Destruction also is like that with everything focused on making Chaos Bolt deal more damage, because ability that does 60% of your output clearly needs more buffs.
Arcane is only saved from this because Arcane Blast is hard cast and Presence of Mind (next 2-3 AB casts are instant) can be used only once per minute. And now Missiles are the new Blast anyway…
The problem: The amateurs pruned all “not spec specific” spells because having some spell in case of being kicked was deemed too complicated for children armed with their parents’ credit cards.
Solution: Giving base “nuke” spells back to casters. Things like Fireball, Arcane Blast, Shadow Bolt. You get kicked in your main school, fine, cast the other spell for a while, then it’s back to the proper spells.
Blizzard solution: Let’s throw darts at board to determine which spell you get which may or may not be useful. And let’s keep all the “real” spells spec and school locked, Ele still can’t heal for crap, and ALL of their spells apart from Frost Shock, Flame Shock & LVB are Nature & MOST of them are hard casts. What can go wrong?
Know what’s the problem with this? The one OTHER Frost spell - Nova - is extremely useful in PvP so you DON’T want to be kicked in Frost unless you’re fighting another caster. And Ice Block is Frost too. Ring of Frost (if you use it) too. Let’s now consider that Frostbolt basically doesn’t do damage when you’re Arcane specced. So:
You hard cast it, the opponent doesn’t interrupt, they basically get ahead in the race to DPS the other guy down. Thus it’s basically bad move.
You hard cast it, the opponent interrupts, if it’s a melee you can’t Nova them, and in any case you can’t Block. Good that you baited them into using their interrupt, just hope you didn’t need to use that Frost spell.
Oh and if the melee guy is on you, then casting damage spells on them is the last thing you need, because they will outdamage you anyway.
Fireball would be better emergency DPS spell anyway…
