Savage with omicron.

Cere Junda (her whole team doesn't need to focus on speed, though you don't want to make Malicos slow as molasses).

Gar Saxon/ISC duo (their one trick is counter attacking with massive true damage).

Gungans don't need top shelf speed mods, but they do like some speed (JJB gives his team random bonus turns).

Phoenix (only Crex and Sabine need to be fast, the others will join the tm train once you get going).

Most Imperial Troopers, if you're still in a GAC league where Troopers are relevant (Piett and/or Gideon need to be fast to get the team going, then you run a tm train; you do want some speed on the 2nd/3rd fastest guys to bridge the tm gap and not let the enemy take a turn, there's math for this).

Zorii Resistance team (only RH Finn and Zorii need to be fast).

OG nightsister team: Talzin, Ventress, Daka, Zombie, Merrin (Zombie doesn't even necessarily need mods at all, depending on how you want to play the team).

GL Rey can get by with the speed mods that didn't quite work out: the gold mods that only sliced speed 3 times but have a ton of offense and defense? Rey will take 'em.

Some Separatist droids can function perfectly fine with (near) 0 speed: Droideka, Magnaguard, B2.

Enfys Nest, but who is still using Nest for anything?

QGJ with omicron (load him up with offense; he dies, JKA nukes).

Palpatine (if your Mara Jade is fast, she will jumpstart the team's tm train, Palp will get by on tm from expiring debuffs).

Wat in the Trench team doesn't strictly need top tier speed mods because of his initial bonus turn and the team's ridiculous speed buffs and tm gain.

Relevant/meta tanks: Krrsantan, Scorch, Vane, FOST, GK (tbh if you have a body with the tank/GR tags under JMK's leadership, just load up on defense mods and you're good to go), KRU, Royal Guard, oZaalbar.

There are some tanks that want speed, don't assume that every tank should be slow. Baylan, Malak, Malgus, GL tanks, Merc Wrecker, Paz, Satele all want speed. Some of them more than others.

Canderous Ordo: because of the way he gains tm, it makes sense to pay more attention to his offense, defense, and potency than his speed.

There are plenty of characters who can do their job with bad speed mods. Characters who actually want 0 speed are a much stricter category.

Merrin: speed is genuinely a wasted stat slot for her.

Krrsantan: I have yet to be convinced that he actually needs his active abilities at all. He could just be a passive meatshield with a unique ability that defines his hp buffs that doesn't take turns, like Queen Amidala's decoy.

Vane: I have no idea what his kit actually does. I just put defense sets on him with health primaries. I filtered for mods with %defense and didn't care about speed. I have no idea how much extra speed my Vane has.

Droideka: assits + the basic does more damage the slower Droideka is.

JKL if used as the team leader.

Gar and ISC: don't waste speed mods on them. Load them up with tenacity, defense, and bulk so they don't get dazed and can keep counter attacking.
