I've recently started doing beast tribes. Everyone knows it's just another daily thing, and pretty monotonous in general. Kill some things, gather other things. While some have some unique things, like the whole dream thing with the pixies, but it's generally all the same. I haven't done beast tribes in current content since I'm going back through the game to get them, but so far it's been... really really boring. I know it's side content, but even the rewards suck.
I'm doing Heavensward beast tribes at the moment, with the Vanu Vanu and Vath at level 6, and I've completed all the ARR tribes so far. I don't know the full shop for Heavensward beast tribes, but if it's anything like ARR it's just... lame? It's a good excuse to put crafting mats somewhere where you can buy them instead of farming for them, but after it taking SO LONG to finish the ARR tribes all my crafters were already 50+ and I had no need to use the vendors other than grabbing the minion and mount. Not to mention, if you level using leves, the restoration, or other turn ins then, again, they're useless.
To talk about mounts... SO MANY TRIBE MOUNTS SUCK. It's cool for a while, and then I swap it out for a cooler mount and forget about it. I've seen the endwalker ones a lot and those are probably the best, specifically the Miw Miisv, and other expansions have some good ones like the Portly Porxie, Mikoshi, and the Cloud Mallow. There are others that are very meh to me, but the ones I listed are mounts I would actually use.
The whole point of this post is my feeble wish that beast tribes have better rewards. I feel like I'm doing all this work to just collect mounts and minions, and unlock a dye vendor. You do get some unique glamours, like the sable death mask for doing all the ARR tribes. I just wish there were more of that stuff available in the vendors. Unique, out of the way, GOOD LOOKING glams.
