I dont think reclaim vet calculation is as complicated as mantis laser tickle damage logging and proportionate mass value vet calculations. My intuition tells me that this shoudlt be too excessive of a burden to the simulation. I am a fan of the reclaim log. Useful data to evaluate bos and to make decisions. However, i am personally a big proponent of ditching vet on all non acu units and non experimentals all together as it is only slowing down sim and has zero impact on gameplay. Like even if a battleship gets vet it hardly matters at all. It pretty much only matters on t1 bombers and maybe on strats. An alternative would be to dramatically increase vet effects. I mean we got this ressouce hungry system, why not buff the regen granted to normal units so that it actually matters and micro would be rewarded. Imagine: you micro a tank well and he kills two tanks and gets a vet level but he has 20/280 hp. Currently this tank would just die in the next fight with maybe 30/280 hp, the vet has no noticable impact. Give regen so that he would heal to 150/280 in maybe 2-3 mins then it would actually be worth sending him back for that time and reusing. The slow regen means that investing micro into low tech units is futile because by the time they are healed their tech becomes obsolete.
Anyway. Regarding nerfing reclaim rate: i agree that this is a good idea in the region of a 1.5x nerf. Not more why: because it would make gameplay more slow and stale. Getting reclaim fast and making units from it fast is nice for apm whores because you usually the cap for reclaim grabbing and reinvesting in huge spam vs spam scenarios is apm. With the proposed change its build power. It would make gameplay slower and of course reward the careful surgeon kind of player, but i think that faf has tended to these kind of players enough in the past patches and that sc like apm fiestas should have their place in faf too.
