Guild Wars 2

So to say the least, Warrior’s Grandmaster +3% dmg per boon on their target is LAME. Both strength wise and gameplay wise.

You would need to attach the boon ripping to a Warriors burst to make it worth the Grandmaster trait. Even if you do, a warriors burst doesn’t happen NEARLY as often as the Thief ability and the spammable Thief ability steals 3 boons which is still A LOT. Even if you made a Warrior’s Burst steal all boons, it would still be weaker due to the infrequency.

TL:DR If there was no cd on the burst and each level of burst would steal say 2 boons, it would be equivalent to the Thiefs Boon ripping.

P.S. Maybe 1 boon more per Burst level with +2 more for the 3rd Burst level (4 boons ripped max Burst).
