I find the ice form harder to play and is really usefull with your teammates. The stun and freeze cooldown skills can be deadly when teamup with dps dg. Most people play fire (as myself) because they want lot of kills and underestimate the power of supports skills in a good team. When you play support you don't get lot of kills but you can make your team win!

The TB Frost form is arguably the most powerful hero in the game for all situations.

Exactly! I have specialized in the Frost TB for on-line MP, and I get few kills, but I also rarely get killed. I accept to play a second-line, support role. 

For example, when I'm near a Citadel (mine, or the enemy's), I avoid melee fighting, and I can dish out a lot of damage against the siege monsters. At such a point of a game, when Citadels are surrounded by mobs, the Frost TB is usually of a high level, and he can dish out a lot of damage against enemy troops that are in a compact bunch. (Killing the enemy heroes, though, is not as easy, but the Frost TB can set-up the enemy DGs to be finished off by ally heroes.)

My only issue, now, is that I find the Frost TB a little boring to play. I'm stuck in an efficient support routine which helps my team a lot, but which gets very repetitive, for me.

I always use Frost form and have great success with it.  The key to frost is doing all your damage from a distance.  Ice Rain is just awesome.  Yeah it does a bit less than fireball but the aoe is so big.  When you can damage enemy heroes and simultaneously kill every single creep in the wave without getting near them you know you've got something special.

Frost nova is extremely helpful once you max it, and the shatter effects can help make up the damage difference compared to fire when you're fighting other heroes.

At lvl 20 you should have all ice stuff maxed and fireball maxed to get the really incredible fire+ice skill.  Then just spam all your ice spells, switch to fire, cast fireball, switch back and your cooldowns should be nearly up. 

Get the cooldowns -15% artifact sword for even better effeciency

I have same feeling about fire TB. It's 'just' spam your skills. Mix of fire/ice must be more interesting to play like InfiniteVengeance point out. In a good team a frost TB is really annoying and can make the difference. And when you combine all support skills of your team heroes, you don't leave any chance to the others guys; you can spam stun one after another, freeze touch and silence few secondes after, slows attacks, and ranged skills for finish... This game is all about team work!

It has no cast range, though I think the AoE is slightly larger. At max level, it does the same damage.

favor itemas are so fucking annouying espically seeing as somepeople have none and some people do  it is so annouying

like i say a sedna  lvl 1 game just started with  3300 hp come on that is fucked up dont care what u say that is fucked up

spaming is annouying espically if all u are doing is going 123 123 123 on the keyboard it is like 0 skill

The Ice TB is so f***king awesome

First, you freeze, then you make it snow, and then you blast them for extra damage.

AND on top of that, you lower their speed automatically & when you doze them with snow, making it easier for your teammates to rape.

Yeah, Frost is a bit weak early game, but it gets awesome later on. If you can catch an enemy DG about to turn tail and run because their HP is a bit too low, a Shatter combo will probably kill them. The interrupt being the last cast you make on them is also awesome, because it prevents any "oh crap I'm about to die" spell casts (and it's your finisher move - so if they're using a potion - you stop it, and at the same time, kill them)

IIRC you can fire while moving in ice mode but not in fire, right? So if you are hunting down down your prey ice is usually better.

right but switch sometimes is a bad idea like if ur fire and ur bieng chased u switch ur going to get raped

i usually get frost nova maxed  for  stoping them so my mates can do majotr dmg plus for the extra time in letting my skills recharge
