That's what most retail titan heroes do anyway. I learned from then i'm just teaching others too. It's called element of surprise because ppl expect you to hit them for 400 dmg or not catch them in the beggining. Let's not forget though that a titan with my setup has exactly 53 CON. Good luck stunning that :>. And i doubt anyone can 2 shot a Titan considering 30% hp means almost 3k hp and over 5k cp. That's 8k dmg one must do vs a titan to kill him from 30%. Don't forget that even though u are on 30% you don't loose the cp.... u still have OVER 5k CP . And in case u get on <1k HP just Roar and u get another 30% hp . That's in total 11k hit points one must do to kill a titan from 30% hp. I doubt anyone can do such a huge amount of damage to a titan before he 3-4 shots you. Get only 1 RB jewel with +stun% resist and u are theoretically UNSTUNABLE . I'm not claiming to be the expert in Titans but it's my second favourite class after Dominator.
Why i recommend using frenzy before oly game starts ? Because almost every class can interrupt your frenzy or zealot if u try casting them while fighting. And if he interrupts it you are dead meat. U are on 30%... with no CP, no frenzy or no zealot, you still do some damage but u're on just 3k hp. And let's be serious a Titan is nothing until he reaches 30% hp. You will just get kited till then and shot down. So what's the difference from starting with 11k hit points (30%hp and 5k cp) and getting kited to 3k hit points when u can also get one of your "IWIN" spells interrupted and get 2 shot ? It's a big difference i tell you.
