From my 20 years of experience in OTSes, P2W players won't pay for extra 0.1% or 1%.ou won't really win if your item is only 0.1% stronger
That's what I tried to say
Yes p2w means doesnt matter how much % extra, its p2w
0.1% and 1% boosts are for players that like nice skins (outfits) in game or support server at all (pay for PACC etc.), but these players do not care about 'boost' at all, it can be 0%.
So by adding 0.1% - 1.0% items you get no extra income on OTS. You do not get extra money from players that want P2W and no money from players that just want skins and support your server.
So if you don't focus on P2W players, you should set 0% boost on items. It does not matter for 'not-P2W-players'.
