I'm not against the new casting mechanics in general, but there are a few thing you HAVE to adjust with regards to this.
Since you can't move and cast together anymore, and since the actual casting animation freezes you into place, it's become nearly impossible for mages to get out of an Eruption or Plume zone in time. I've had this happen to me countless times:
Scenario 1:
• I start casting Cure for the tank
• Lava circles appear underneath me
• I IMMEDIATELY try to move out of the way while still casting. (Screw Cure, I need to stay alive, let it cancel)
• Server decides my casting was successful, and stops me in my tracks to make me wave my arms as Cure is thrown against my will. I'm still inside the circle by then.
• Lava explodes with me still on the circle. I get hurt LOTS.
Scenario 2:
• I start casting Cure for the tank
• Lava circles appear underneath me
• I IMMEDIATELY try to move out of the way while still casting. (Screw Cure, I need to stay alive, let it cancel)
• Server decides my casting was successful, and stops me in my tracks to make me wave my arms as Cure is thrown against my will. I'm out of the circle by then.
• Lava explodes with me out of the circle. Server thinks I'm still in, I get hurt LOTS.
Same thing applies for Ifrit's dashes and targeted eruptions.
The only possibilities for mages to actually stand a chance against these attacks are:
• To be lucky enough not to be casting the moment these attacks are announced
• To be lucky enough that the server thinks you're out of the circle when it locks you into casting animation
• To be lucky enough to be standing outside the zones the moment they appear (safe from the start).
I know that this last point can be planned to some extent. There are relatively safe spots in the arena, I know them and use them. But you just can't stay entirely still during the whole battle, sometimes you need to edge out of place for your spells to reach a target that isn't quite in range anymore. Sure, you can move out, cast and go back to your safe haven, but sooner or later, that plume's going to hit your RIGHT THERE AND THEN, and there's nothing you'll ever be able to do about it. It has nothing to do with skill or planning, it's just dumb luck and hoping that black box of a server sees the battlefield the same way YOU DO behind that 300ms client-server lag.
My solution:
Add 300ms to the "warning" phase of Ifrit's area based attacks
I swear, this will actually give us a chance to, you know, MOVE OUT. Once in a while, at least.
Luck-based situations are NOT FUN.
