Let me draw out a situation for you to understand. You say, one skill of yours equivalent to 20% ok, now it would be fair if we miss one skill we wasted 5% of our skill.
1vs1 Eles using Dagger and Warrior using Snife GS.
First, War spot Eles. He use his Auto attack to get 1 hit in. Eles realize he getting hit, and he spot War near. Eles uses RtL to approach him. (5%) while War (0%). War see RtL coming and he is good, he dodge backward (0% skill wasted), Eles miss (5% wasted and put on 40s CD). Since War is so far away, Eles can not use Lightning Lash to attack. So Eles change to Fire (RtL wasted and on 40s CD, 5%, and put Air Attunement on 10s CD). Meanwhile War still get some free shot at Eles ( 0% wasted). Eles use Burning Foot to approach again (10% wasted, RtL and Burning Foot). War is good that he predict the skill coming, he dodge backward (0% wasted and 2 dodge being used). Eles still can not hit the War due to the range of Claw was too short. More Free shot for War. So far Eles has used 10% of his total skill (RtL and Burning Foot), put Air on 10s CD while dealing no kitteno War. War used 0% of his skill in total and 2 dodge and some free hit on Eles.
Then Eles switch to Earth (put Fire on 10s CD and Air right now say, 5s CD still), using Magnetic Grasp with the pray that please hit him (15% skill wasted and still no dam). War getting hit and being immobolize (0% skill Wasted, while waiting for endurance to refill). Eles approach with Magnetic Grasp and hit War with dams. (15% of total skill being used, Fire and Air put on 10s CD and the result is tinny bit Dam from Magenic Grasp). Eles proceed with Ring of Earth and War get hit and apply Bleeding, then Earth Quake to KD War and Cast CE like normal (in total of 30% skill). War oh no, I am being KD, and his endurance has been refill for at least another dodge. He dodge the CE at the very last second (2.5s when Eles start to cast) cause CE to miss. Eles best burst skill has been missed just like that.
OK War decided to still keep distance with Eles because he know Eles has no more Mobility skill (RtL is on 40s CD, Eles can not switch to Fire due to Fire still in CD), so he start with Cripple Shot. Eles being cripped and start slowing down. Now Eles has two choice, either use Cantrip to clear condition or Tune to Water to clear condition. Eles decide to go to Water (Put Earth on CD while Air is off CD). Then Eles go to Air but because RtL is still on CD and with Switfness from Arcane, he is barely able to catch up to War and War decide to change to GS and use Rush and Whirlwind Blade to keep a distance. Then he switch back to Snifle and keep getting free shot at Eles, not to mention all other skill with Snifle and Aimshot. Eles approach too close, ok here go Snifle 5 to knock Eles back and hey Cripple him, and keep getting free shot hit.
In short, that is what happened. Please tell me if anything in this sencario that I overlooking and that you can not pull off in real fight?So how many skill Eles has to be wasted to be able to hit War just once and not even stratching his armor a bit? (15%) + Free shot from War compare to your 20% skill wasted, I would take over 20% skill wasted + Free shot hit anytime.
Conjure GS, I believe that is what you are talking about. It take 2s to Cast and can not cast while Moving. The only reason Eles pull of the GS like you said is to run away which means Eles already out of option and that is the last resort. But being stay still while low health, any class can finish Eles in just 2s and there you go, Eles never get a chance to get away.
