Well kind of difficult to explain. Most of us know that targeting a mob in a mission is quite difficult with the tab-key, if you have a teammember of the wrong faction.
Well today, I have encountered another gameplay disturbing situation. Our base (ql150) got attacked. So we jumped to our base. There were not that much people around, say 15-25 or so. The first thing I usually do, is to blind my opponents, so I pressed 'tab' and cast, but ... PvP-lvl-limit, can't attack. I tab again .. same thing. Some will say, that I should use the mouse, to target my opponent... well I would, if the movement of the mousecursor wouldn't be that laggy and framerate dependand in those situations. And on top of that, you cannot always target an attackble opponent, because there is a crowd of low-lvls (or too highs) between you and your victim. Even tabbing until you get a 'good' target may be impossible. If lots of players of the other side do not stand and keep walking around, you'll tab to the same person several times.
Even if low/highs will not be able to buff each other, they can disturb a fight by just beeing present. They cannot attack me or my tower, they can't do anything, but they are still there.
So please change the way 'tab' works. Or give us another key for that purpose. I want to select the next attackable opponent (mob/player), of course regarding gas, level and faction.
