T-54’s are definitely being used in Clan Wars all the time. As scouts, obviously. A more cookie-cutter “build” actually looks like 1 med, 3-4 arty and HT’s.
I really don’t see a way around it, it’s the nature of the games like this. If you have 15 slots, you want to fill them up with tanks that do best at the role you are going to assign them. And there is always “the best” tank for the role, otherwise they are all just copies of each other with different skins.
So there you have it - Maus to push through (although he is a less and less popular choice nowadays, when everyone shoots gold thanks to stupid promotions), T30 or E-100 (with gold rounds) to support and kill stuff, IS-7 to get to places fast and hold there, T-54 to scout (not THAT much needed, really, since everything came down to 1-2 tactics per map now) and to find an arty or two if they are lucky.
Whatever you do, say you bump up the Jagdtiger so it can push so much better than the Maus that even lack of turret doesn’t matter, you will be just replacing one “top” tank with another one. In our example, a whole bunch of Maus drivers will be angry.
TD’s would have to be insanely good to replace the current top damage dealers, which would screw up random fights.
The same goes for meds - in the environment where the maps are static and the tactics on them have been perfected for more than a year, there is not much value in scouting, no room for a surprise attack pretty much, med swarms dont’ work anymore for like 3 months now and meds’ straight damage is irrelevant. Meds are powerful in a chaotic unorganized environment of random fights, where they can exploit tactical mistakes and opportunities. Tactical mistakes and opportunities are pretty rare in CW by its nature, so meds lose their main advantage.
The 7.0 changes to CW are going to stir things up a bit but all they do really is force people into having backup top tanks, which most of the active CW players already do. Except for arty, hehe, people will definitely need to grind up more arty (I wonder what it’s going to do to the random fights) .
The main problem of the CW fights is their predictability. If every CW fight would be fought on a completely randomized map, people wouldn’t be able to develop tactics ahead of time, wouldn’t be able to assign roles and pick tanks ahead of time, there would be a huge need for scouting, etc., all of which would result in more varied team setups. But of course, in this day and age, it’s completely unrealistic to expect dynamically generated random maps in a game like this.
CW is a completely different game. Completely different skills are required. In some cases, for example, you are NOT supposed to try and shoot at the enemy. It’s more about devising a plan, having resources for it and executing it perfectly. This is absolutely NOT what random fights are about. And IMO it’s impossible to balance out these two games so that all tanks are viable and balanced in both.
