You may have a point about rogue-centric campaigns, but (regardless of me getting carried off with my rogue-rant) my main issues with CR/EL are:Hussar said:An all rogue campaign is pretty far outfield for core rules to be covering anyway. I'm unsure why people would want rules that covered such corner issues. CR is what it is - a shorthand baseline for picking creatures.
1) It might be a bit deceiving if your party has a different composition than normal (i.e. 2 paladins and a cleric on a holy mission, or a ranger, a barbarian, a rogue and a druid fighting threats to the Forest); lacking one or more of the four basic D&D components (fighting, divine magic, arcane magic, thievery) would make certain monsters harder to defeat and more taxing on the party's resources than the CR would suggest.
2) It assumes a 4-PC party; while this could be solved by adjusting it to the number of players, that is calculating the party's effective level by dividing the sum of all levels in the party by 4 (for example, you have 3 party members, all at level 4, you'd have and effective level of 3: 3x4/4=3), is this an accurate adjustment? Would a 8-member party, for example, be exactly twice as powerful against monsters than a 4-member party of the same avarage level? This seems to me as more of a problem at smaller-than-4 parties than with bigger-than-four parties, as the smaller ones would usually be less diverse.
3) It assumes a 3.xE magic-level and amount of magical items; it is far less accurate on higher-magic settings and, even more so, in lower-magic setting (including ones with 2E assumptions, read the High Level Campaigns 2E sourcebook to see what I'm talking about).
All in all, it is still a good "eyeballing" method for balancing encounters, but it has several pitfalls in practice that the DM should be aware of to use this successfully.
