The game is suppose to be fast paced and they have a grenade that can leave you out of the fight for 14 seconds. Increasing burn rate and decreasing the damage by 1 would most definitely balance it out. And sorry for the confusion maybe a better wording is viking funeral is OP not the firebolt grenades themselves. Since you main a warlock you are showing a very big bias towards them. I'm not gonna win this fight of course because you think your right, but a grenade that can keep people out of battles and at low health for 14 seconds, and basically be a mini tracker at the same time is indeed OP. The trade off is basically none because the 2 perks that effect the grenades that make them oh so OP, also effects the melee and your super, with 2 perks you upgrade all main parts of your subclass. Now have a nice day bud. Keep the bias train rolling!
