Firstly, just because of lack of competition does not mean that we do not have to hold the game to a standard.
There is the Wargaming VS Gaijin argument - I am one of the many players that originally left Wargaming in favor of Gaijin and what Gaijin presented at the time with War Thunder.
Yet, competition or not -
- WoW brought back WoW Classic (and had to revert some money changes to preserve the classic experience).
- CoD Brought back Verdansk Hype.
- BF2042 brought back skill-based accuracy along with some other major changes they reverted to be closer to the older games.
- Destiny 2 had to revert sunsetting weapons.
- SWB 2 reverted LB and pay to unlock (P2W) mechanics.
- GT7 reverted reward balance and economy.
- Diablo reverted build nerf and cosmetic charge.
- WoT reverted decisions on premium ammo and damage handling.
- World of Warships still ongoing with the post-anime ignorance and still reworking some changes.
That is just the first ones that come to mind. Comparing decisions to other titles like Arma (who said sorry, but we promised something we can not do) and Warframe that implements changes best suited to maintain balance between game design intent and player “fun” the contrast is a bit stark on what should be-, what can be- and what is- happening.
Right now in WT it appears that linear play is encouraged, wallet spam to grind is encouraged, lack of team play is encouraged and vehicle design, immersion and indoc is ignored in favor of (again) pushing linear play.
