A thousand times yes. It's not on the devs if someone chooses to follow a theme and refuses to change their power selections and slotting to improve the build.
Again, it's not on the devs if you refuse to change your build or playstyle to utilize Venomous Gas properly. And yes, along with poison trap, it is arguably the best power in the set.
2 powers with -to hit are defensive powers.
Asking about the number of cones was because you said
I'm well aware how many cones, TAoEs, and PBAoEs poison and water have, and
is completely irrelevant specifically because of what you said about staying at range and using cones.
I'm arguing against changing the way a power functions purely because you don't want to change your build or playstyle.
Then I guess I'm not a wise defender, cuz all my poison uses for holds is VG and poison trap, didn't even take the ST hold.
Uhhhhh yeah, it's called
Weaken, envenom, and VG all give -def, -res, or reduce the effectiveness of defense buffs. Whirlpool also gives -def. Water burst and geyser do KD and KU respectively. Can't use MoG or Unstop if they can't get back on their feet, and even if they do, thanks to reduced def and res, the AoE damage will finish them off.
