planning to be a glady STR/CRT/AGI(maxASPD)

I personally think it's a bad idea. At 140 agi, and 1 vit, you would have around 3k base hp when you become gladiator and your evasion won't save you. You would then try to wear hp gear to increase survival but it lowers your dps so you would look like a high lvl glad with low dps and can't tank.

You might want to visit the gladiator section in this forum to learn more about builds and skills.

Your stats are good for another class (like ninja maybe), so you might want to push on with that as a farmer char and build another char to be your gladiator.  If you can afford to reset, then you might want to live as AGI/CRT for leveling then switch stats to CRT/STR/VIT when you feel you have enough stat points to distribute.

I've met some gladiators who went maxASPDAGI/STR/CRT who were disappointed with their build.  Some tried correcting it by adding VIT, but although you gain survivability, you fall behind in DPS compared to CRT/STR/VIT builds.  Eventually, some of them made a reset and are very happy with their builds now.

An important skill for gladiator is Counter Attack, which means that you should build your gladiator in a way that it can take some hits.
Glads also have regeneration skill (LvL 180 skill) which helps you survive longer.  I was able to solo boss grind alot better with this skill.

Future Glad skill will have AOE, which will allow you to attack multiple mobs and kill them fast, but this won't happen if you either have low DPS or low survivability, or worse, both.

I don't understand your question.

With counter and berserk, you will kill faster than agi/crt without a doubt.
