You are welcome friend. Some more details about the benefits of Premium Account:
Most players focus on Research Points (RP), and the bonuses that Premium Vehicles and Premium Account give to RP’s. HOWEVER, in my opinion, the Silver Lion (SL) bonuses are far more important. Even if you research a ton of new tech tree vehicles you will most often be slowed down by lack of SL’s.
ALSO! You should really purchase the crew “Expert Training” with Silver Lions on vehicles that you like, and plan to use often. I simply do NOT play any vehicle without purchasing the crew Expert Training. It increases most of your crew skills for that vehicle by something like 50%, or more if your crew skill is low. (If you have any questions about Expert Training, let me know.)
Then, another excellent benefit of Premium Account is the “insurance” against losing ANY SL’s in the event of a bad match:

Text if you need to use a translator:
insurance: compensation of the expenses for automatic vehicle repair, automatic ammo restocking and Crew Replenishment up to zero Silver Lions in battle that finish with negative earnings
So, even if you were to buy a premium vehicle, you can STILL lose SL’s from bad matches! That is 100% impossible with Premium Account, so no matter how badly you play, or how bad your team is, you will NEVER lose SL’s from bad matches.
Just another reason why I always advocate for Premium Account first, then get Premium Vehicles if you still want them 👍
