2) apologize thought the casttime debuff came from magus but that would probably be another class ability .(doesn't change the finality some destro class can debuff Castime).
3) let aoe radius to tinkerer and reduce tick interval to grenadier
my proposal already solve lordroom issue ,
(Btw we are still waiting for someone who can prove this is really an issue)
To be clear I'm nit here to deal with destro or to nerf keg . I just try to understand destro PoV , and fixing their issue (keg heal out of party in lordroom)
If my proposal limit keg heal stacking out of party , then I try to think about new keg mechanics to making keg usefull and attractive in a new way , I don't want keg being less usefull.
You can't ask for keg to be targetable since anyone can interrupt keg cast , force order to fight out of keg range (really small 30feet) , and if keg got buff from turret simply destroy the turret would already affect keg either .
If you remove some mechanic from keg you have to give something to keg in return . Keg is not broken , it work as intended imo.
