I do not understand your points that well. And to relate it to a vehicle that “does not exist” but clearly also exists as F-16s exist in game in multiple trees (I am not sure if the AJ is modeled in anyway differently) is not fully equivalent. Or should Japan not have anything to use when at least there is a acceptable link here in my mind (and to be replaced when suitable replacement is added, as was done in part to Maus), and the caveat of hiding once this is resolved?
It is funny as most players you view in the Maus have amazing stats in such a “poor” vehicle with issues (I only went so far as unlocking since there was far too much to do in game).
Era-differences mean nothing in a game based upon performance in the WT environment, and for the most part it works well, just skewed by the popularity of Russia/US/Germany and how this makes nation’s vehicles harder to compare.
The Maus does not suffer, it was removed because it is hard to balance such an odd vehicle (world moved on clearly), and that is was only ever added due to different situations back in early GF days and people wanting Germany to be competitive against the only other nation in game with GF, but the game moved on A LOT since then and they handled it well with “in game, not a normal acquirable, but still available to keep us happy”.
God you lot make me want to come back and pee about with vehicles again… but I remember the players so thank fk for the forum to scratch that itch xx
Edit:
I have never found the +1 BR MM unworkable, this appears to be just how people approach the game/grind with odd expectations. If you don;t like +1 then use vehicles built for +1 and remember most of the players on both sides are EXACTLY like you can can exchange with one another, not the 4 players per side in possibly better vehicles (but also might just as easily play like poor AI). But MM is a different subject.
Heavies in the past were ALWAYS generally: Good in Downtiers, Bad in Uptiers, with Germany having the guns that can hold it up like the Tigers, or USA having the Jumbo where the stability, and dumb way players use the map/vehicles, allows for the weaker gun but trolly armor from giving them some life in the +1. The situation with Heavies starts at 1.0 and not really something to worry about for the most part.
