- Britain: Guild of Arcane Arts: +5% Spell Damage Increase
- Jhelom: Bardic Collegium: +1 Faster Casting
- New Magincia:Order of Engineers: +3 Dexterity Bonus
- Minoc: Maritime Guild: +2 Hit Point Regeneration
- Moonglow: Merchant’s Association: +2 Mana Regeneration
- Skara Brae: Mining Cooperative: +3 Strength Bonus
- Trinsic: League of Rangers: +3 Intelligence Bonus
- Vesper: Guild of Assassins: +5% Swing Speed Increase
- Yew: Warrior’s Guild: +5% Hit Chance Increase
Minoc isn't exactly a "maritime" city; Vesper or Trinsic would make a lot more sense for that one.
Skara Brae has literally nowhere to mine; Mining Coop doesn't fit that town very well, imho.
Just because of where the ranger's buildings are located, League of Rangers only really makes sense to me for Skara Brae, not Trinsic.
For Britain, Society of Clothiers fits a lot better imho, as a kind of 'generalized benefit' than arcane arts. Arcane Arts imho would make a lot more sense for Wind (see below).
"Guild of Assassins" - that name would best fit Buc's Den, though +SSI still doesn't feel like a good fit for that name imho.
Now, if we remove:
Society of Clothiers: +1% Resist bump to all resists (Since buffs will not go over caps)
Guild of Healers: 5% Bandage Healing Bonus (5% healing bonus is really nothing)
No need to remove anything; there's still 9 towns without a governor that exist in both Tram and Fel - Cove, Delucia, Buccaneer's Den, Haven/Ocllo, Heartwood, Nujel'm, Papua, Serpent's Hold, & Wind.
Since there's 9 virtue towns as well, it'd be easy - just let each city adopt a 'sister' city/town which is (RP) either under their protection or influence, or in a 'mutual defence' agreement with them. Say Vesper and Cove are paired; citizenship in Vesper would allow you to pick either city's benefit.
So now instead of getting rid of 2, we have space to add in 7 more new benefits. There's still 27 guilds whose names weren't yet used for a benefit:

Association of Warriors
