Welp since I am the only active person interested in this game, on this site at least, might as well make an update to my progress.
I made it to the next German Heavy tanks in the Maus line. the VK 45.02 A. Its a fun tank, you have to play it right though as it is more a medium hunter than a brawler heavy tank. Its gun pen is sub par compared to same tier heavies, but it makes up for it with speed, being closer to a medium than a heavy. In terms of armor though it can quite easily bounce same tier medium guns when angled, and with top turret. So yeah, its meant to just flank, and try to either overwhelm mediums, or remain a target of least priority so you can flank the slower heavies.
I also have been moving along the Leopard 1 medium line and am over half way in exp to unlocking the indien panzer. the current tank, the VK 3002 D is fun, and out paces the panther in speed, but doesn't have the panther's amazing long 75mm. You can load either the L/70 75mm or the L/56 8'8cm. One has better pen and lower damage, and vice versa for the other. I prefer the L/70 75mm for is reload speed, and its more reliable pen. While it can't take anything from the front with its pen, its more forgiving hitting the sides. the 88 in my experience bounces more often than not, so I tend to stay away from it, mostly because I hear many that do use it just load Premium rounds to compensate, and thats not worth it to me.
I am looking forward to the Indien and plan on buying the Lowe at some point as well just to have the set of unique round turret German tanks.
