Im pretty vocal on comp PvP especially as mentioned solo v teams but that could be due to player count. I still think the penalty for a loss is too much and the grind to great, I get that stuff shouldn't be given away but at least make it feel like more casual players have a shot.
Destinations, I haven't been in the dreaming city or the tangled shore for anything other than random strikes( which I have enjoyed grinding) for ages, don't see the need. I'd actually rather flesh out a few less destinations especially terrible ones like mecury, wtf no sparrows!
I'd like to see raids more fun and less mechanic heavy tbh since late desriny one I really haven't been bothered to do them I want to have fun when gaming not be a professional sweat, I could care less about world's first just make it fun.
Weapons mostly pointless not since early d1 have I had a need to look further than my usual loadout for pve and PvP other than to do triumphs, in PvP especially change stuff up likely outcome you get destroyed. I remember in d1 changing weapons mid activity as it was beneficial now I have whole weapon types I never use. Most weapons are vault trophies.
Gunsmith pointless.
