Not really. Ward of dawn is not that good in pvp, but good enough! Recently, I played crucible (thorn bounty) and summoned a bubble. 4 of my teamates went inside, and the enemy team got too scared (We had lvl 28's and a 30 I think ). After that, one of the rival guardians decided to enter the bubble, with his comrades following him. [spoiler]it became a massacre then.[/spoiler]
