Our party doesn't use this tactic but it is not something I would put above our DM. I personally don't think this is that bad as our party could could fairly easily figure out some way to deal with it. First off we are not stupid enough to allow the fight to be conducted this way, and nobody would willingly stay in the sphere of darkness.
Step 1 would be for the spellcasters to come up with a way to stop this. If no Dispell magic is availible a alternate spell could be cast to slow him down. We would likely cast any 1 of these: Entangle, Plant Growth, Web, Any of several Wall spells. This should slow him down enough and cut him off so he will not be an imediate threat. Are these cheesy, I don't think so, these are all around usefull spells not just counter spells and we have at least a couple memorized at all times. Using spells to break up a fight into manageable bits is just good tactics.
Step 2 once he is slowed Area effect spells would be launched at the center of the darkness. This will either kill him or soften him up for later.
Step 3 our fighters would avoid the darkness, or run though it on the edges, and go after the other members of the party especialy the spellcasters. They will continue to stay out of the darkness as best they can. If the darkness returns to follow we would continue to move the fight out of the darkness, since it is unlikely the spellcaster is giving everyone blindsight. Remember that Darkness effects his side just as much except for the Rogue.
Step 4 once the other members of the party have been dealt with only then will we focus on this problem. With the long durations this may be a muti-step problem. If we can not dispell the darkness, we may let the rogue live for the rest of the day and deal with him the next day when he will no longer have the blindsight spell. If we have another Rogue or Barbarian or a Blink, blur or displacement spell, or some summoned creature who can locate the rogue in the darkness, we may send someone in to fight.
The person I realy feel sorry for however are the spellcasters. The real problem is not the Rogue but the person buffing him. If I had to deal with such an enemy and wasn't prepared for it I would flee until the next day. Possibly that night or the next day I would strike again, this time putting everyones full focus on the spellcaster, if he is taken down this will no longer be a problem. This time we would use the steps 1-3 above and the spellcaster is going down this time, then we can decide how to proceed with step 4.
This does not seem all that big of a problem for the smart foe, or even the somewhat less smart ones. Only the dumbest of creature will stick around to fight in the dark if they can't see. If the foe doesn't have a counter right away why are they sticking around, Why won't they retreat and come back later when they can counter.
Are these Ideas cheese, I don't think so, just smart tactics. And since when are smart tactics cheesy. as a player I would be personally upset if every encounter was stupid enough to fall for this, leaving me bored repeating the same fight over and over. Once or twice I could see this working, but if my DM didn't counter and force us to keep changing tactics I would not want to continue.
