Which units?
The out of meta units were buffed to the point, where they are appealing alternatives, like RETs or M5 quad.
Out of infantries, there were only toning DOWN of units, like con weapon slot limit or bren nerf.
The patch notes of last couple of patches do not seem to support your claim here.
Indeed, brens were nerfed, IS have their bonus RA in cover removed, Royal engies had their RA nerfed, and vet 3 reinforcement cost increased, Cons lost a slot, Pfusies now lose a slot when they upgrade to G43s, Volks flamenades have a timer now, Penals had their vet 3 RA nerfed (when they got PTRSs) moving cooldown nerfed and reinforcement cost increased, Rifelmen can't have double 1919s and had their vet 3 RA nerfed, bundle grenades/light gammons were nerfed, heavy sapper armor was nerfed, assault engies had their 0.9 RA moved to vet 1, Lieutenant had its BAR removed. I probably missed some, can't be bothered to look through all the changelogs.
Hardly "only buffs and no nerfs"
