In 10 Thunders we have:
McCabe who does min 3 on his ml6 (built in crit), which can alternatively ignore Armor, HtW, Incorporeal, HtK.
Lynch and Huggy who both have the potential to do min 4 damage and they come with Illuminated who do a min of 4 damage on their ml when damaging brillianced models.
Kang, who has a ml7 attack with min 3 damage.
Yasunori who has a ml6 attack with min 3 damage.
Izamu who has a ml6 attack with min 3 damage.
Obsidian Statue with a ml6 attack with min 3 damage.
Mr. Graves with a ml6 attack with min 3 damage.
Jorogumo with a ml5 attack with min 3 damage.
The faction has enough choice when it comes to models with min 3 damage, with more access to positives flips on attacks (built in and through upgrades), than any other faction. So why the argument that we need another master with min 3 damage? I play guild in addition to Ten Thunders, for access to masters who do min 3 damage. And that's what those masters do. They do the damage and the crew brings the support .
I play 10 Thunders because I want access to masters who aren't one dimensional. Masters with fun movement and positioning tricks. Masters that offer support and can do damage. Masters that can summon. Masters that allow me access to other factions cool toys. All these things also win games.
If every faction has masters that do the same things, there would be no reason to have different factions. Every faction has weaknesses and every faction has strengths. If the day ever comes where Malifaux goes the way Warmachine went, where every faction had access to all the same kind of tricks and toys, the game will become stale. And then you'll find people asking "Why does faction "X" now have this? That was faction "Y"'s thing!" instead of "Why can't faction "X" have this? Faction "Y" has it!". And in my opinion, some of this has already started to happen.
