Yeah, well designed target tables are missing, penetration is sometimes a bit retarded. But COH 1 had the infamous 5% crit bug, ppl could live with that.
As for your replay, all of us seen insane things in COH. OMCG being useless/usefull, sniper missfires etc.
It also had retarded hit or miss sniper fights and inconsistent off map arty damage vs structures (Inf doc arty vs Wehr T2, Firestorm on 105 in earlier patches)
