ZOS, seriously, why don't you remove them?
Give one justifiable reason (a good one, not something like "to look cool while questing") for any player to have a Monster Helmet that, theoretically, is supposed to enhance the game experience, be it helping in dishing more damage, debuffing more or sustaining better on longer fights, to have it in Preposterous or Training Wheels traits?
I know, I know, it's only the first 1/3 of the day but, for example, I ran Fungal Grotto I countless times (since it's pretty quick) trying to get the Kra’gh Dreugh helmet and, although I would prefer it Medium or Heavy I would be OK with Light at east for a start, but not with literally useless traits.
Now imagine Magicka users that will want the ("un-dyeable" >.<) Valkyn Skoria or that other one that looks like a condom face (sorry, it's true) that have to run a loooooooong dungeon just to face an RNG trolling.
I would go further to remove those traits from ALL sets, specially now that World Bosses got much harder (and fun), we have A LOT more players farming everything increasing the respawn timers and we can't sell the loot anymore (which, IMHO, was another bad idea)
You're keeping them, fine, but you could spare like 10 minutes to defend, even if briefly, your decision because, honestly, I can't see any reason other then keep players running the same content over and over again. I thought this was a game, to be fun, not preachy.
