I mean, when you're making all existing gear bottom tier and lowest possible power AND then making the cost to upgrade it to usable level so prohibitively high... this is Red War vault nuke levels of cost. Upgrade cost for me is getting to the point that this has effectively sunset my entire vault as I'm not sure I can be bothered to level anything up as it's objectively worse than new tier gear, and 'new' bonus system. I miss upgrade modules - they weren't perfect but at least you could at a sensible rate choose to use the gear you actually wanted to use in endgame activites. Right now we're being railroaded into only using 'new' gear and grinding a very small subset of content as the only sane upgrade price is when using higher power of the identical gear to upgrade - ie. there are NO sources of cheap upgrades for any non-new gear.
