Well... I'm a bit bored with this much complaining. I just really took care on the factions thing here once, when I joined my thief into the TB. On that moment, not the TB, but Minax and Council were controlling the actual sigils (I stole all of them and put them into the TB's stronghold, even if they got later stolen from our stronghold by the council members).
When I stole them both of the other factions (minax and council) were having sets of vendors + guards protecting their stuff... (in fact, minoc's sigil that was under minax control was the hardest to get, as they placed guards around the sigil and vendors around the guards so nobody could enter stealthing in there (unless it was someone smart enough).
Now I see people complaining because the TB are using THE SAME tactic as it was being used by other factions... just ridiculous.
1) Yes, you are revealed from stealth when you run on the vendor, but nothing prevents you from hiding inmediately after...
2) Yes, you need to wait until your stamina is recovered again... but who says you need to be visible for that?
3) Stop crying because someone uses now the same tactics as you did before...
