We have tested the tiger extensively, because after initial implementation in our maps, we too thought the tiger was 'weird'.
We've taken pot shots at tigers from many distances on arad with T34/85's and vice versa. We've put our findings against the data we have, and from what i can see, it's correctly modeled as far as our current models can take it (we dont have a molecule perfect modeling of armor, but what i get from Alan, we plan on making the models even more extensive). We knew people would be screaming hell about the Tiger, but we ran with it anyway, since it is correct as far as we know.
The main disadvantage we have is mapsize/distances. I can compare it to the Mod's infantry against most Ostfront infantry battles. In the Mod distances could be so small in a lot of the MOD maps, even nades and bullet balistics seemed weird. If you compare the core gameplay on Konigsplatz for instance, you can actually see the various weapons function to their properties, so propper even, that i hear sappers scream for a rifle instead of the default loadout
It's a hard bargain: either we model the tanks unrealistically to counter the 'short range' map sizes we can make (<1000m tops at some odd spot), and up their armor specifics and downgrade their ballistic capabilities to suit the max size maps we have going, OR we make the tank maps even bigger, with larger view distances, even less detail, and having 32 players max on 3x3 km maps killing the servers and your computer and the fun; neither options are good for us.
There is 1 map where the tiger meets T34/76's. Due to the scenario's at hand, we ended up with mostly late war tank maps, the only map where there's T34/76 and 85's up against tigers is Ogledow. So please, go test with T34/76's and the tigers there. The only problem there is that the map is fairly small. I'd say test it from left to right, you should be able to fire long range shots in that direction. Make sure its the 76 though, it's got a smaller turret.
We will probably visit earlier war tank engagements in the future, where the tiger will live up to it's 'hype', meaning, it will be meeting early war russian tanks.
But still, it's not the machine that makes the killer, it's the operator. I can do pretty well on a Tiger on Arad, as long as you use it as a 'rifle' and not an 'smg'
Your key asset is your driver, and that goes for almost all the tanks in Ostfront. Good driver > Good Armor.
