Balance in HotA.

Regarding balance, I'd like to add (and I agree with those who already mentioned it):
1. Reduce the effectiveness of logistics specialists.
2. Remove the free ballistas and cannons that heroes can recruit from the tavern, unless they are available from the first day of the week.
3. Increase the growth rate of Hellhounds in Inferno to 7. Then Fiona will be a viable alternative to Kal'ku.
4. Remove the spells Teleport and Armageddon from the Sanctuary.
