The theme has come up a lot in other threads, but as its a little hidden I think an extra thread is in order, if not merge it at your leisure.
I have thought a bit about the Law Enforcer, and come to the conclusion: At the moment, taking it out is PUNISHING you XP wise. Why? Because if you are just once killed while trying to level you loose time to get your imps in, to get back to the place you were, repair things, etc.
That can't happen if you let the LE inside your head.
The only incentive is the extra brainslot, which for most isn't worth it till late (I tend to take that thing out at 0/2 or close, because I think its right, but thats just stubborness).
So, if not for conviction, most people would agree I think, that if something has more negatives than positives, that you can easily see, then you will not do it.
But in the end taking LE out should be more attractive.
The solutions might be many, but the old ones in a new coat would do nicely.
1) You pay for your protection (Slight deduction from Money gained from Mobs)
2) If you take the LE out you get Risk Compensation XP wise. I mean you get MORE if you take it out. Not less if you let it stay in the head. The wording is important here, no punishing on that side for LE Users. Take the XP gain of now as basis, and those without LE get e.g. 20% more / faster.
This should naturally also be engraved on the Law Enforcer itself, that you will be rewarded with more XP for taking it out.
Coincidentally it also helps those that think they level to slow.
I am sure there are more ideas out there, also i am sure that the gap should not be too big, as playing LEd should still be an viable option - but it should be MORE attractive for many to take it out, not LESS attrative than with LE as it is at the moment.
And please remember: For the most parts, Players just randomly killing you is not the thing I said why letting LE in is more attractive right now.
MAKE TAKING LE OUT REWARDING, NOT PUNISHING PLEASE
