I've been messing around with soviet tanks recently, and I believe they can use some fixes.
1. The scope reticle. Please give IS2 and the TDs their historical sights! The current reticles leads me to believe that they are a direct copy from the german ones. Yes, this isn't a big deal, but imo giving tanks their original reticle is important. On a side note, the Panther's sight reticle is also copied from Tigers'.
2. The MG crosshairs for both the T-34s are off. Their crosshairs aren't even close to where the actual shots lands. I don't know if reto purposely made it to be like this but I do feel it's negative impacts to be somewhat annoying.
3. I would personally favour the idea of introducing tier 3 medium tank destroyers and eventually Heavy Tank Destroyers. Yes, I am aware of reto's Armor 2.0 project and thus adding new armored vehicles is clearly not a priority, but I would still like to suggest some viable candidates. They can possibly be imbalanced, but hey I'm just sharing my opinion with our community. <3
Medium Tank Destroyers, Tier 3
US: M36 Tank Destroyer (90mm GMC)
Germany: Panzer IV/70
Notes: These tier 3 tank destroyers features devastating firepower compariable even to that of heavy tanks, but still maintaining speed and armor similar to the standard of medium tanks.
They lacks anti-personnel capabilities, with no co-axial MG and none (SU-100) or one MG seat that has either limited turning (Panzer IV/70) or no protection (M36), just like the existing TDs. While these beasts certainly packs some serious punches, they generally have reduced or same mobility as tier 2 TDs. They will also have a vastly increased maintaince cost for obvious reasons.
These TDs will certainly affect both staged and war games and can even be made into the separate Heavy Tank Destroyers category if they won't fit the medium armor games well. In this case, they will be the first tier of Heavy Tank Destroyers. A 2nd tier and even possibly a 3rd tier of Heavy Tank Destroyers can also be made, but there are very limited candidates and can result in serious balance problems.
US: No Candidate (T28/95 can be, but it didn't see any combat thus making it a very bad option)
Germany: Jagdpanther(Good option imo), Jagdtiger(Bad option due to imba), Elefant/Ferdinand(Somewhat imba), Nashorn, 10.5cm K 'Dicker Max'(Bad option since they're basically glass cannons, would go against the 'Heavy' category)
That concludes this post for now. Thanks for checking, and I really hope the suggestions (1 and 2) would be reviewed by Reto! =)
