Would a Zerk/Soldier Nade build work?
Grenades still do decent damage on power-crit but not the full max potential you get from conditions.
But would it ‘work’? Yes I think it would, maybe other than the highest rankings pvp or highest level fractals.
But for anything ‘normal’ I’m sure it will.
A lot will depend on what else you can do.
Since you mention condition removal i’m going to guess you want it for pvp or WvW.
If so: in WvW it will work for sure. Freeze grenades are your best friend anyhow in there…
For pvp I’m less experienced to say up to what level of play you can pull it of.
Wiggely, wobbely and other wombaty wabbity creatures…
