My only problem with firebolts is there is no countering it when you've been hit, your counter is to run away and leave your trials team in a 3v2 for about 13 seconds, more then enough time for another firebolt to come at your team. There is no reasons for there to be a 3 sunsinger teams... With every other grenade, there is the drawbacks. Lighting grenades you can step out of, Incendiary you can step back from and not take as much damage, skips you can run from, storm nades you can step away from,
