The biggest culprit are some units that are so powerful, that they have become a no-brainer:
- Is there ever any reason not to build the Sniper?
- With that pricetag/versatility, is there ever any reason not to build at least one 222?
(This leads to sniper + 222, and some fluff units around it).
However, a nascent culprit is that OST lacks sidegrades:
- Their cost is integrated into the teching cost.
- However, lack of sidegrade options takes decision-making away from the player.
The only real decision an OST player can make is between T3/T4:
- Do I forego T4 and stick with T3?
- Do I skip T3 and jump to T4 (only on certain modes)
- Do I completely skip teching, since I have Stug-E's in my loadout?
USF can choose among:
- Faster teching
- Nades
- Racks
- Healing
UKF can choose among:
- Faster tech
- Racks
- 5-th man
- Bofors
- AEC
OKW can choose among:
- Healing
- Puma or Luchs
Soviets can choose among:
- Cheese
- Cheese
- Cheese
- GTFO
Being a combined arm fashion, it's hard to recrew weapon teams.
Try using an unupgraded halftrack on the field. It works wonders to maintain your field presence. No, it's not as good as mashing the T-key WFA-style, but it works just fine for capping/recrewing team weapons.
Halftracks are, literally, the only advantage EFA factions have over the others when it comes to this. I am not sure why people don't use them.
