The entire point of running Archers in offense is that they deal high single-target damage over the lanes, eliminating Ogres, Wolves and Defense Beasts very quickly. What this boost does is kills a group of archers you have (or something like that) to turn them into 1, much bigger archer. This is counter-productive and totally the opposite of what you want, which is spawning as many of them as possible, especially at the early-stage chokepoints that are meant to prevent your units from spawning. Archers also keep those Cannons at bay, killing them, ensuring your other units actually get out of the tent and can move forward without dying.
Idk who came up with this idea but it’s totally not what this unit, the Archer, needs or wants. It actually reduces the effectiveness of regularly boosted Archers and it’s extremely annoying, because there is no way to turn that boost off. Nobody needs their 5 (or whatever the number is, this game has always failed in the description and ease-of-understanding departments) Archers to die, turn into one big guy who dies just as easily, because it reduces your total Archer DPS and punishes you for running Archers in offense in the first place.
Please change that pro boost to something that’s actually an improvement over the regularly boosted Archers and not a hinderance. I honestly cannot find a single reason for this pro boost being positive.
