T25 Pilot marathon

In case you didn't know, it's a marathon event going on right now.  15 days, a new task every day, 24 hours to complete.  Each one gives you a reward, they vary from "coffee with buns" to a garage slot.  If you complete 13 of 15 missions you receive a tier VIII medium US tank T25 Pilot and a 100% crew for it.

The missions so far:

1 - win 5 battles, be among top 10 players;

2 - destroy 10 enemy vehicles (any amount of battles);

3 - make 15k damage;

4 - 20k xp

#4 (today) was the hardest for me, took about 2,5 hours.  I used my fav T-67 and Nashorn (tier 6 German TD.  Hate it but need to do it for nice tier 8 of that line).  No premium, just hourly "personal reserves" for xp and such.  I was collecting those for a while. You can use tier IV+, but of course it's much easier for those who has tier 9-10 tanks.

I imagine next tasks would get more and more complicated.  I'll see if I can do it...  Any way, the tank is... ok I guess.  I don't have any tier VIII prems.  Would be nice to try one.  If no - hopefully I'll receive at least a garage slot.

P.S: Of course you can buy the same tank at the premium shop.  Or buy 1-5-all daily missions to open it.  I don't plan to do any of that.
