The server as a whole seems to be dying (the Constant). I'm hoping they are thinking of merging servers soon because it's pretty pathetic how empty everywhere is...republic fleet rarely passes 75 people during prime time.
If the Imperial outnumber the republic 4:1 on your server, that would have the Imperial Fleet pushing 300 people on prime time? On my server we are normally looking at about 1/4 the population on the fleet at any given time and I would assume your server is in that ballpark(WoW seemed to be about the same as was Rift). That would have peak population during primetime in the ~3K region- that isn't anywhere close to a server merger level. I played on a launch WoW server that had ques for new content, free server transfers with every new expansion due to overpopulation, and it was about at that level during a normal day. That is assuming that the 4:1 ratio is correct.
That Khem dude is suppose to tank and he can't tank for shit because I have no way of healing him during a fight. So I have to tank my own fights with one of my other companions healing me. Leveling slows way down then.
If you don't like doing it that way, roll two dps and kill them faster. Yes, I have a 50 assassin. The game gives you flexibility, as long as you don't suck horribly then you can play it pretty much any way you want(dual healers on a healing class is kind of boring and takes a long time, but other then that the combos all seemed to work).
Overall companion tanks leave something to be desired since they're not particularly resilient and prone to breaking CC
Shut off their AoE and they won't break CC(although they can't tank packs of mobs very well at that point). I've had Xalek tank level 50 normal mode flash point bosses and didn't have a problem with the amount of damage he took(he filled in for the tank we had, he was better geared, that was on my Sorc). HM's would be a bit much, maybe after I get him in full Columi gear....
Anyone seen patch notes for 1.1.4 live yet? Been looking around, really hoping that Soa gets sorted out, getting sick of getting to him in 45 minutes then taking twice that long to get him down because he bugs out so many times(although sometimes he doesn't bug and goes down easy, meh).
