LOL at the crying noobies qqing about balance.
OST is the strongest faction in this game, as it been always, you just need to get gud.
Now that T4 is so cheap, late game is a breeze.
Here we go again with random aggression. Don't assume you know everything. And if you're going to say something, put some effort into the post and explain. If not you might as well not type or add to the conversation.
If you're talking about team games then yes, T4 is cheap, but so is everything else since you can actually safely rush it thanks to 2-3+ teammates. In smaller games, it's still not viable, especially when Ostheer has no way to force the enemy to react to give themselves breathing rooms aside from 222s or certain doctrines. Getting T4 is easier, but the vehicles except the Werfer are still expensive and means more time for the enemy to run around.
Ostheer can be strong, but it requires flawless micro and good positioning if you're not going cheese-meta aka call-ins or relying on snipers and snipers means less map control for a faction that will generally have less map vs everyone but Brits.
You can't afford bad engagements or you'll have a hell of a time trying to retake ground as Ostheer excels at holding, not assaulting until T3/T4. Furthermore, you've got to be prepared for light armour which means less AI which is needed for factions like USF. Finally, Ostheer units, until you reach tanks, are mainly glasscannons. You cannot sustain damage for long, hence the need for good positioning and micro, though bad RNG probably hurts Ostheer the most.
As to why I like Ostheer when I play them. Combined-Arms, diverse units, strong defense (barring RNG), and it probably feels the best winning with the faction as it probably has the least cheese aside from Snipers (less so now) and 222 spam. (I don't even touch call-ins as it's too meta)
