The Dragon, for example, has 218, and he also doesn't suffer much from retaliation.
The Miner has 262.
Cassia has 250; here too, retaliation can be a problem if small amounts of damage start pouring in.
Tiraxor has 157 damage per hit, so yes, attacking is risky. But this is only the case with griffins. In other battles, the ability to deal 314 damage is a significant advantage.
For example, Greck won't be able to take a mini-outpost, but Tiraxor can. There, you can get about 300 damage from a rush, meaning with expert offense and a couple of levels in attack (~360 damage), you can already try to take it.
And in the "zephyr" maps, +1 speed (compared to +0 for Greck) also makes capturing noticeably easier; in the smallest and second-smallest maps, stacks are already being defeated with a single hit (without reducing retaliation).
