Keep in mind that i play since about 3 and a half weeks, so all of this is written from a beginner's perspective. There are a couple of things i noticed that need change:
EBR: What the fuck is this? They should be nerfed, 50% less health for all models across the board. If people want to lightspeed around like morons they should be a 1-shot for strong td or heavies. Also let us damage the tires…There need to be nerfs of some sort, they don't even fit the game in the current form.
Mines: It feels like the team that spawns south loses 90% of the time since they cannot get fast enough into the castle in middle. Terrible map, CLEARLY needs change.
Artillery… A max of 2 artys per game, maybe even only 1. Obvious reasons.
Premium/reward tanks and ammo. Money is not an issue for me, i do have a problem with the balancing though. Some standard tanks are simply unplayable. If i see defender, LT432 or even 279e and i am in a normal counterpart-tank i get a headache, just examples. Yes those tanks should be strong but some of them are too strong, it's very apparent, even for new players.
Overall i like the game a lot, i am completely addicted and love to grind the lines, but the game needs some serious balancing. I don't know how wg plans on attracting new players when there are so many holes in the game-design.
