It would be nice if the guild buff towers scaled with the person using them.
Right now, all of the buff towers have static/fixed values and as we all know, fixed values are really only helpful for lower levels. ie, attack tower @ lvl 10 is +1200 patk/matk & that's great for a lvl 1 toon but doesn't seem to help much when you already have over 100k patk or matk.
One option is to have the tower to add the greater of a fixed value or a %. ie, from levels 1 to 10, the tower would add +1% to +10%. Using attack towers again, the current fixed values are: 100,160,220,300,400,520,660,820,1000,1200.
So a level 1 attack tower would add 1% of your current attack OR +100 the moment you touch the tower; a level 10 attack tower would add +10% or 1200. This way, the tower benefits everyone and scales up.
Another option is to add a % to a fixed value. ie, a level 1 attack tower would add 0.85% + 100 ; level 2 would add 1.7% + 160 ; level 3 would add 2.55% + 220 ... level 10 would add 8.5% + 1200
Once again, it helps everyone and scales up.
The main difference between the 2 approaches is that the first approach would perform a comparison between the fixed value & the % vs the 2nd approach would be a simple calculation without any comparison.
