Is there a keybind or macro that you can run that will distribute shields faster than the standard 'Distribute Shields' option? Not as fast as TacTeam, obviously, but I see people without TacTeams taking Alphas to their shields fairly easily because of their distribution. I'd love to be able to drop my TacTeam, but as it stands, I need it to withstand Alphas/being focused.
They are probably rolling at near max shield power. That's really the only time shield distribution can with stand the stronger alphas.
That and they might not be using the shield distribution keybind macro. Remember STO has a very difficult time managing simultaneous commands so when you bounce space bar to balance your shields and fire weapons, the game invariably is going to take one command and ignore the other. (usually the secondary which is in most cases Shield Distribution) So in effect, you are hindering the effect of shield distribution, by binding it to space bar for the sake of ease of use.
IIRC, the facing-specific shield distrubtion powers are slightly more effective than the regular distribute shields. So maybe that could be something to keybind (but obviously, not to one single key, but rather 4. Maybe SHIFT + ASWD?).
