Love all the changes except the time reduction and WT buff
IMHO, you guys have thought out a lot and are doing really awesome changes to make the CoC experience better. All the changes seems really very good (I am a max TH9 with L30 AQ and L23.5 BK, so don't know/care about TH11 and TH10 changes, hoping we will NEVER get TH10s in a TH9 war). But I am doubtful about the time reduction. With the map size increased, the time increase was mandatory. At TH8- it is OK, but TH9+ needs the extra 30 seconds as they can use the extra space given. At least keep it in middle ground, say 15 seconds more or TH9+ getting +30 seconds.. something like that.
Also, WT is already the most fearsome defense, and *significantly* increasing their HP seems very scary (unless, this *significantly* is the same *significantly* as you guys increased the league bonus, +20 DE :D). Apart from these two, all changes are awesome.
