I feel like he’ll back me up in this analysis:
Titan is the best general-purpose class in the game. Here’s what you get:
- The hero is a Giant so it starts with 50% mana.
- Stun opponents if they do skull damage to the hero.
- Start battles with a Duststorm active.
- Barrier on Brown matches.
- Explode a random yellow gem on 4/5 matches.
- Immunity to: Stun, Poison, Disease, Death Mark, Devour.
If, instead, you take the Thief class to try and get Goblin synergy, what you get is:
- 50% mana start.
- Deal 7 damage to the last enemy on 4/5 matches.
- Hunter’s mark a random enemy on 4/5 matches.
- Summon Bandits when an ally dies.
- Cannot be targeted by Spells.
- 30% chance to dodge skull damage.
- 7% chance to instakill a not-immune last enemy when another enemy dies.
The thing is, Titan is more on-plan for Irongut. You want to boost his attack so his Devour rate is as high as possible. That means Earth’s Fury, a Red/Brown weapon. Both classes have a 50% start, but Titan can lead with a Duststorm. And if your first move is a 4/5 match of any color, you get an explosion. That’s likely to cause a brown match with a Duststorm active, and that’s how you cast Earth’s Fury on turn 1. This is a very aggressive plan. Overall Titan gets and generates a lot of mana via Lightning Strike.
Compare that to Thief, which is more focused on longevity and incidental damage. A good Thief team wants to generate tons of 4/5 matches and milk the Sneak Attack trait combined with Rising Shadows. The combination of Stealthy, Dodge, and Backup help contribute to the long game. But none of those things make Irongut more effective or easier to boost. The stat bonuses for having an all-Goblin team are negligible.
Thief 100 with Irongut will still be an effective team, but Titan is able to easily threaten a turn 1 Attack boost plus the ability to recast very quickly. Thief is more about making the battle last so long repeated casts are likely. In my opinion, the faster you win the less often your opponents will win, so Titan wins because it doesn’t want a long game.
