Remake COH1 or do nothing. COH2 strategic depth is too shallow and too nubs friendly, it's beyond salvation.
I'll tell you why you feel that way. In CoH1, Axis had the brute force and Allies had the gimmicks and tricks like Sticky Bombs and Greyhounds that could flank and deal great DPS at the rear armor; giving you a reason to flank.
In CoH2 Axis has the better of everything and then some. Sturm Offiziers, Command Tanks, Artillery Field Officer, Panzerschreck, Pak43, these stuff are wholly unique for Axis (could list more) but Allies don't get much, leaving them with a bland faction design that banks on the Axis player screwing up at some point or overwhelming them through repetitive, memorized tactics executed by using doctrines used countless times.
So yeah, give the stock Allied factions some ground to stand on and you'll find the game will get better. Of course, if you want the insta-pin MG's from CoH1 and you call that strategic depth, then your opinion of strategic depth is twisted and not really something I can agree with. Just being cautious here.
