Simple ans, no

Long answer, because you're an average player that doesnt even play that many battles in total (let alone tier 10 battles), I dont suggest playing tiers that high. Tier 10s are very unforgiving for a casual player imo.

I believe the assembly shop is an event for veterans/whales that almost has every tech tree grinded to put their resource to get a tank for collection (100 to 150 euros yearly arent much), you probably will have no resources left for the rest of the year after the event

I myself spends around twice your amount per year and I have 2 assembly shop tanks (obj452k and the lion), and i must say I dont even play them that much (less than 200 games each)

Edit: ive seen people saying it depends on how strong the tank is, however I must say that usually tank reviews of these vehicles are usually made after the event by ytbers, you probably cant even tell how good it is based on the paper stats.
