With armor and HP trinkets you can take X amount of hits (say like 5).
With the same armor but no HP trinkets you can take Y amount of hits (usually it's 2).
Suppose the defense of the armor is changed so that you can weak armor without HP trinkets and take not Y amount of hits but X amount of hits, next remove trinkets from LD so that everyone can take X amount of hits.
The survivability of former HP trinketed players remains the same and the HP untrinketed players now don't die in 2 hits making this game much more enjoyable while not reducing players to squishy blobs of easily smashed goo.

The only real complaint would be from those who use non-HP boosting trinkets (not that I have seen more than 1 in my entire time of playing).
Removing trinkets from lockdown is a bad move, as it removes the need for a monthly "subscription" to Three Rings by means of energy. Hence, reducing revenue. They're a business, so we should let them keep making money.
Getting 800 energy a month isn't that hard, plus during the holiday months we can get a bunch of boxes to open and get more slots from, or buy cheaper from the auction house.
Making classes take or lose more from trinkets would be a better modification, such as strikers have -1/3 health from every health trinket but +1 from sword trinkets and -1 from bomb trinkets. Recons could have no health modifier, +1 gun and bomb trinkets and -1 sword trinkets. Guardians could have + 1/3 from health trinkets, -1 for gun trinkets, and +1 for bomb and sword trinkets.
Maybe we could take out the -1's for weapon trinkets, but it makes players further optimized for their class.
Overall the main problem in lockdown with trinkets are strikers with no health penalty. Making penalties apply across items would be a good fix.
Second biggest problem in lockdown is offensive bonus balancing, but health trinkets are the bigger issue.
