I already had max warp at 80k, so my warp % was only 1.5x and it also cost 108 diamonds. Seems that it costs the same, to raise the warp to max, if you're at the last tier. Not sure how this works out that someone can buy a 1.83x warp for the same price it costs me to get a 1.5x and the same price it costs someone else to get 1.2x. This all seems messed up somehow. =/
