strength ability stacking

let me tell you about the strength ability these so far only 3

the first one gives you 10% more damage for 5s the second one gives you 50% more damage for 7.5s and the last one give you 100% more damage for 10s

the strength kit gives you a % of your damage

(the first one gives you 75% of your damage) with ability 1 (second one gives you 100% of your damage [so double damage] with the 50% more damage) and the third one gives you 125% of your damage and 100% of you extra damage

however every time you do an ability you lose some of your strength what you started off with its the range of 1 to 0.1 loss

(i dont rembmer the right amount on the dot but its close to that.)

if they stack do you think its too op? (keep in mind if they stack they also make you lose a %
(if they stacked you would lose about 3% of your damage in the end)
