Repulser brace is -blam!- because void shields are -blam!- and you wanna put a cooldown on it ? Naw, it already only lasts a coups of seconds. Remove the cooldown from Destabilizing rounds period and leaver Brace as is, no need to nerf Titans either they've had enough nerfs thank you. There are other perks with little to no down time that do the same thing, but better. Incandescent and Voltshot, have no cooldowns so it makes no sense for Destabilizing rounds to have one. There is no need to nerf anything here, just pure buffs.
