They tried to address this, but failed. I recommend just resigning yourself to it not getting fixed.
Or run a build to deal with it. Drain/purge then pewpew, also if your team focuses on one ship then switches and then switches, the healers can't heal everything. Keep hopping forcing them to change target, and you can take them out easily. a team can pump out more damage than a healer can heal. You just need to focus it.
You can't exspect to be able to take out people playing as a team when your not.
I will have to agree with Brother Belial here,there are counters to deal with it,and the most valuable of them all is the teamplay.
I dont play tacs as main,but they've been nerfed during the past months actually.Also,you should realise that Dreadnought is a team based game.The commands in this game are for a reason,such as marked targets etc.
