I
REALLY think this is a very solid idea. Bots are pretty subpar once you get into raid tiers (clerics only seem to cast a heal every 6-7 seconds or so...), so there's no real impact on upper progression. Not to mention that bots generally aren't permitted in raids anyways, so it would be far from game breaking. I think the ability to summon two bots would be
amazing for us soloers out there. There are several classes which are really really limited in their ability to solo and are out shined 20 fold by the more popular classes that can solo, like SK, Pally, Mage/Necro, Beastlord, etc. Permitting two bots would let people take on the menial things like LDoNs and kill tasks without the downtime that simply doesn't exist on those main stream classes.
In general, it would make the server much more fun for those moments when your guild is primarily offline and you're stuck semi-afk, waiting for someone to log in. I know you gentlemen have considered this before, and it was likely very gamebreaking earlier in the server's life when T1 was endgame (yes, I was around before then

) but at this stage, it seems like a very logical and FUN implementation!

Please please please consider the function of permitting a second bot!

(Honestly, if I could make ONE suggestion on improving the server, this would be it, although it would have to be limited to two...)
