Condition Tracking can be extreme. But you can't remove them either, because then combat will quickly turn boring or repetitive as you reduce the tactical depth.
A stylistic thing - I love the teleportation powers in 4E, but maybe they are a little too many at heroic tier? (Not that I would want the Assassin without his teleport between Shadows ability from the start...)
Both good points. I find condition tracking easier if I encourage my players to describe their actions instead of just announcing their power names robotically. Better plot/battle immersion increases my ability to keep track of 'fiddly bits.'
For teleportation I agree, but its definitely a feature not a bug in 4e. I considered trying to scale back the amount of teleportation, but realized that I'd be judging the merits of scores of powers unless I just did a blanket keyword restriction.
