I think gladiator's dodge forward bash should stun
Currently there isn't much of a mixup with glad. His skewer is too slow to be used in duels, and doesn't really add any pressure.
If glad's forward bash had a stun, then it would be more effective as it would be harder for people to just react to the attack.
I feel that currently gladiator's skewer still isn't really that useful as a tool, because with variable dodge attacks, people can wait to see if you're going to GB before inputting the light, meaning you can't punish most assassins for feinting the skewer. It's even worse when it comes to bash heroes.
I think this is the overall problem with testing grounds, it doesn't give enough time to work on iterations. We get one testing grounds, then whatever they decide after is the final product. Testing grounds needs to be faster paced if they ever want it to work the way they intend it to work.
