I really like Gladiator in some game modes, but I'm sure he needs a little tune up.

1. Replace
Intimidate with Roots. So we can have a little energy control.
2. Make
guarantee crit hits to his special attacks while he is unblockable.
3. Add
immunes. It seems to me that immunity to
shock and
incinerate would be suitable for him
I'm sure this little changes can make him
great champion. And it's very easy to make.
