Poison and invisibility are again in Last Chaos. Those 2 are your best friends in PvP. Here you can get the cheapest last chaos gold. Hyde Step, DS, DM. Run! Dash have a long range (if Rk is 70) If he is lower then 70, use hyde step and Dm again on him. Rk miss a lot on rogues too. Triple Bash hurt a lot, if they can hit you. They have a good def, that's why poison is needed, while they do not have a lot of evasion, so if you have good daggers, you will hurt them. You can try to pet shield. But personally, this technic is not fair at all. You can use the same tactics for the titan on the Rk.
In Last Chaos, Templars you could a lot more now. Don't underestimate the TK. Their both stuns are a pain. If you kite, they will teleport you. They have a lot of defence. Tanking them would be the most stupid thing to do. Try the tactics you mentioned above. He stunned you? Do not cure the 1st stun. Tk have a lot of def but a low attack. Even if you are 3-4 level (lastchaos money) lower than the TK, you have more attacked them. Therefore they will make Mana break on you, their only attack skill, and a lot of chance that this skill will miss. Then they have only normal hits.
Finally they will use their 2nd stun to cure it, poison death motion, invisibility. You need to do it quite fast before he decides to tele you. They can have a lot of def buff, as same as the titan here. Their skill cost plenty of time before reloading. Once they tele you, it take a while before they can do it again, and you have to re-target em after they do that skill. You killed a level 95 TK while you were level 90, you was not maxed, double strike level 5 and hyde step level 5 only, you had only 2k Hp when you came in arena and you killed him, and you had 1,3k Hp left when he died, he healed, and you never used any healing pots. Their def are a problem but not their attack.
