Skill help

Mentalboy1

Hi I have a lot of skill iso. Who is best to spend it on? What's people's thoughts? My thought are.
Blade almost maxed out his regen is good
Fury is handy , good with quake synergy
Hawkeye not used since other champs been better. Feel like he should be ranked up for his power drain and bleed
Winter I would like to rank a 5* but costs more
Aegon is good but with ranking up?
Gwen pool is good
Massacre is fun now awakened and have diablo for synergy
D devil not used him yet
Spidey is good

I also have two awakening gems are any of these worth it? Heard Aegon is but what is the advantages ?

Thanks
Spidey
