I think theres no need for TH11, but it would be cool to have some individual challanges, if you reach certain goals... You can gain ''bonusses''
For example, reach X attacks during 1 season,
Or after destroying X inferno towers
Your troops gain 5% extra health, or do 5 % extra damage
YOu can gain several bonusses, but can only use 1 at the time in lower TH levels, and 2 at th10
