I maxed ALL my Skills, and in Tarian Raid we are getting quite good SP.
Means we are collecting SP on and on and on... but we can NOT use it for anything.
So my suggestion:
Add a NPC to the game, that allows us to buy stuff with our Skill Points!
There should be requirements for the shop, like lvl 160+ (lows need their SP during the game and ppl couldnt "exploit" the shop by lvling toons to the 60s, making fast+alot SP in ToF, making new char etc).
could be handled easily by expanding 'Black Tyrant Ramslo Assasin'-Affinity.
Max. Affinity value could be 500k, at 500k a SP-based Shop opens.
Items in shop could be for exmple:
lvling Pots, new kind of Boxes(like the Boxes that are selling in other Affinity shops like Lakin Guard or Sin Killer), Reform Potions, maybe new jewels like move/attack speed, upgrade stuff etc
That would be a pretty interesting and unique idea but I fear the potential that it could create a even deeper divide between ap buyers and non ap buyers, considering you can get up to 400+ sp on certain raid mobs with a pssp/spb, people who can afford to spend could control the market even more for greater benefit.
But once again, its a unique idea and I do support it, if a bit hesitantly. As long as the rewards are not that big or if pots that are gained, are account bound crit pots, adren, pbi, stuff like that.
Any type of move speed/attack speed gems would further unbalance game though, and reform potions dont need to be flooded into the game. The boxes could give out the new 146+ upgrading items but once again, that could potentially be a bad idea.
