- Some lag, not INSANE lag. But still
- Abilities (and light attacks) not going off. Sometimes with resource drain, but not always. Sometimes dodgerolls helps, if you can even do it.
- Crashes. Often in certain spots, and/or when you simply approach a keep.
- Long load screens, especially during battles - making you end up dead on camps, or keeps even being turned before you are out of them.
- Inability to mount, in very extended "combat" - even if you sad violin music have started to kick in. Forces you to cross the whole map on foot.

For the "in combat" glitch, it's TERRIBLE on templars. Worse than any other class afaik. Both stam and mag. And it seems to work a bit like this (for all, not just templars):

1. Enter combat with an enemy player.
2. Leave the battle, or your enemy does
3. Enemy does NOT die, but remain in combat
4. You remain in combat for as long as the guy you previously fought is alive and in combat

Not entirely sure this is the case. But quite a few times, I've suddenly left "combat", when I know the enemy has died. Sometimes you remain in combat because a group member or their pet is still in combat too, but I guess we all know that.
