on top of tagadas point, on maps where there are many rocks (10-30 mass) inbetween broken trees, I would assume such a mod to prioritise the rocks, enableling a player to massively increase the reclaim rate on such maps, which will change the meta on such maps. the reclaim is hidden in trees for exactly that reason.
Any changes that add prioritisation are not acceptable from a balance perspective since they will break the meta/balance on some maps.
"Advantage in the beginning of the game can snowball into big advantage, it is not so important from what rating exactly people have necessary apm in average. It favors click spam like some game on smartphone where you do nothing but click as fast as you can. No tanks, units, nothing but clicking."
this only matters if a) you are actually able to capitalise on the extra mass instead of just overflowing it, having no e , not noticing youre having idle facs/engies... (classic <1.5k issues)
b) you dont get a dissadvantage from not spending the time on sth else (e.g. not noticing youre suiciding 19 tanks into 20).
on high level there only rarely is actual coockie clicker reclaim after min 3 or so (youve nothing else to do before that anyways so clicking reclaim actually saves you from boredom there...)
