Suggestion: Allocation of talents
Here's my suggestion: Allow us to control the distributions of stats from talents (up to maybe 40% per hero).
This means you could have 40% of your SOS talent on main, 40% on adam, 20% on blood and 0% on the rest for example. This will mean you won't have to share SOS with your mages and your mages won't have to share the IM talent (up to 40%- although 40% is an arbitrary number I made up).
This is intended to give everybody a power boost... it will make them stronger... people will use this to their advantage...
I fear the upcoming comments, but let me know what you think.
