Gotta agree with @strudelle I think eternal could use a rework. I understand people don't want the rank to be too OP but until you've played an eternal account it seems a lot more op than it actually is. It's actually rather underwhelming/not noticeable over other ranks. Would like to see if the 19% drop boost works as it seems worse than the other ranks with a boost.
My droprates have been worse since getting eternal I think my tob went from like 1/15 to 1/28 and chambers from 1/10 roughly to like 1/15 (which i had a better rate as legendary lol) i go what feels like 15-20 dry every purple drop whether i do it on boost/boosters etc at cox while other ranks see similar or better rates. 2% drop rate extra for 50b (or thousands of dollars) is not really worth it especially when you see people with 1/10th (uber bis which is why a lot of people dont go over uber) your rank and a similar/better log. insert "ujusthavebadrng" but most eternals seem to agree.
Most high end donators dont really need perks like the farm contracts, slayer task select and dense essence blocks,pc points, vote timer etc (unless low xp mode or going for 200ms/new accounts). 5 new skin colors are nice since i enjoy cosmetics but they get stale since there's only 5, the title is interesting but again not worth 50b to upgrade from immortal.
The unlimited swaps are nice if you plan on making and committing to new accounts as you're locked in for 3 months but not everyone will utilize that.
Eternal is mostly a flex at this point as it offers not much over immortal yet is double the price so even seeing new exclusive skins/cosmetics/icon colors under your character etc for eternal donators would be something to compensate for spending 100b/20k if the perks such as droprate or raids rolls can't be buffed.
So no support on a new rank as our best rank is underwhelming already. I couldn't see a 40k rank adding much that's over eternal to make it worth getting without being too op. Would support reworking eternal donator though.
