Even though quite a few game mechanics have been added and improvements made, I believe the overall experience was better in the early months of OBT.
Moscow was mostly bolt action, with the weapons like PPD box mag and MP-38 actually being powerful and desireable, in tank combat you would constantly see (and even fear) BT-7, T-26, Pz 38t, BA-11 - all those were early war babies by WW2 standards but in Moscow they reigned supreme which felt awesome.
Everyone didn’t have vitality perks and 3 explosive packs on each soldier, there was no constant fantasy MKb-42 and PPSh-41 spam, Terminator-50 camping on the other side of the Quarry, no premium BS like the MG 13/Lewis squads with 0,00001s reload time, there was no possibility no place “cool” decals on your tanks or make crazy customization combinations for your soldiers to “stand out”.
Additionally, the killfeed and scoreboard weren’t filled with ‘marshal’ and ‘general’ stars icons, silly name decorators with fires and bombs, it all looked more serious and even classy.
One of the very first reasons why I got interested in Enisted as a whole was the “basic” and “boots on the ground” feel of defending Moscow with Mosins while wearing mittens an driving shitty little T-26s in a hardcore last stand.

And now, partially due to the general concept of progression in this game (higher level unlock = more powerful), partially due to the devs seemingly trying to milk the vanity and ego of the players by offering all kinds of bells and whistles to be “individual”, partially due to more and more rampant fantasy/paper guns added (AS-44 and Fedorov Berlin, MKb-42 Moscow and Stalingrad) and premiums, the game has been going down the path of higher unlock automatic weapons spam, bolt actions left for bots and hardcore fans, as well as looking more and more like a cheap Chinese mobile game with ☆△ASs44enjoYeR△☆ in the killfeed.
TLDR: early war stuff was deadly and feared, gameplay felt brutal and basic, game looked less cheap without various decorator icons and customization, there were no OP p2w paper guns
