I like to give my thralls greataxes and greatswords for PVE stuff when I’m grabbing a bodyguard.
Base Melee guards: Full strength or vitaility gear, depending on the thrall (Teimos gets vitality, berserkers get strength etc etc). All heavy armor because I can. No armor plating, though. Too many resources for so little gain. I’ve found that once they hit the 1k armor mark, the plating really doesn’t matter. The only armor upgrades I give them are weight reduction kits or durability kits, depending on whether or not I plan on wearing their armor at some point. Weapon Kits, however, are priceless. There’s literally no downside to them if given to a thrall. Master Weapon Kit or Advanced Weapon Spikes depending on the base armor pen.
As for base archer guards, Heavy armor in the form of the Poitain cavalier/Hykerian Raider set (minus helmet) and the assassin’s hood for a +10 bonus to accuracy. Grab a bunch of Freya’s and Hundred-Arrows, give them cooked fish to boost that accuracy stat, and give them the best bows I can (aside from the ones I plan on using). Master weapon kits on all bows.
Thrall pots for base defense are your friends. Especially during a purge/raid. Gruel vs No Gruel can make or break a base assault.
Base archers: Chase distance 15, Attack distance 50, Attack everything, and put them in positions where they have 360° firing arcs, My current favorite method is a fence on a foundation/ceiling and using the Derketo DLC’s stage floors. It works out extremely well.
Base Melee: Chase Distance 50, Attack Distance 30, Attack everything. Half are given spears, a quarter are given maces, and the remaining quarter are given greatswords/greataxes (depending on my mood)
This next part may not apply to you, since it’s a PVP server that I play on, but I keep a box of Obsidian arrows, Poison arrows, and Snake arrows on standby. My heavy hitters get obsidian arrows to punch through Armor, my cannon fodder get Snake arrows since they’re cheap and easy to replace (both the thrall and the arrows), and my “could have been good but weren’t” thralls get poison gas arrows. When I have a feeling that I’m going to be raided, I give all my thralls gas masks of some kind and proceed to dole out the arrows. Will the archer thralls kill a player? Probably not. Will they prevent them from healing by peppering them with single digit damage? Absolutely. Also, obsidian arrows are easy to craft by the thousand, and when given to a strong archer will pack a heck of a punch
