robertliguori said:3.XE was a step in the right direction; the use of monsters with ECLs as well as explicit class abilities to get monsters on your side. My hope was that since the rules encoded that, for example, druids could enlist the services of thoqqua briefly, that core material would being to operate under the assumption that parties that included druids (or prepared casters of any stripe) past a certain level could use thoqqua-abilities for their own ends.
Thoqqua have the magnificent ability to rapidly bore through solid stone and leave tunnels behind. This, needless to say, is an extremely useful ability for a dungeon-delving adventurer.
Now, the 2E/4E mindset, this isn't an issue; thoqqua burrowing ability isn't on the list of PC abilities, so we don't need to worry about it. But what happens when, through cleverness, a PC does manage to gain control over a thoqqua? You have, in essence, replaced whatever higher-level challenge encoded into the solid stone the thoqqua is now melting at speed with however difficult it is to gain control over the thoqqua. Now this sort of thing can be exciting and interesting. But if you want to have dungeons the PCs can't casually burrow through with a decanter of endless water and a cooperative/coerced thoqqua, you either need to take the monster ability into account, or find some way to foil the cooperation/coercion. But even if you do manage to do so in-game, remember that in-game problems have in-game solutions; if you rule that the thoqqua builds up a resistance to charm spells on account of its long domination, not only must you remember this rule for further charm spells, but you're not stopping the PCs from nabbing another thoqqua and starting again.
First of all, there is NOTHING in 3e that differs from any prior or future edition of D&D regarding this so-called "problem".
3e tried to to codify monsters into a HD leveling system that mirrored PC leveling. In 4e, the designers have jettisoned this clunky system for a new one in which the designers just give monsters the cool abilities they should have without worrying about advancing it per some formula (that didn't really work well anyway).
There is NOTHING inherent in either system that prevents or encourages your so-called "problem". A 3e 10 HD monster having ability X, is the same as a level 10 monster having ability X in 4e. PCs manipulating monsters to their advantage can occur in either system equally well or not. The degree to which your "problem" exists is going to be DM and campaign dependent.
