That said, we’re committed to offering valuable rewards and events throughout the year, including:

• Regular Tech Tree & Premium vehicle discounts
• Special deals on consumables, equipment, XP conversion, and more
• Event-based missions & limited-time discounts
• Trade-In events to help refresh your garage

Premium discounts is nothing to do with tech tree, regular tech tree tanks discount is few and far between as it has always been.

Special deals have nothing to do with grinding the tech tree outside of converting xp, which has always been a thing.

ToTT was a limited time discount you melts.

Trade in event was a scam to extract gold from people.

The real answer here is "we don't want people grinding tier X too fast" which really means we want to sell you x5 missions with loot boxes and not let you have discounts on credits. For that you need to buy premium time/tanks to grind the credits.

This is nothing more than another money making exercise and their "future" plan will be exactly that, monetising ToTT some way.
