The shield was a cool feature that promoted tactical use. Jumping was useful in a lot of situations, lockdown was nessesary all the time but a major disadvantage.

The solution is not to remove it though (it really fits the TR theme). The solution is simply to make it very fast to switch in and out of (less than a second setup/down time) and or make it really amazing like Dviddleff says.
