I disagree. Mega Taiga and Snowless Taiga are actually decent. Would you want only taigas with snow in them? Also I don't think Mesas are that good looking in general, but they are a good way to get clay. Savannahs aren't super good looking, but they are actually okay.
Roofed forest biomes, IMO, are ugly and kind of suck. Lots of the other biomes, such as tundra, have this charecteristic.
Don't feed the troll. If they can't be bothered to support their opinion, don't respond to them.
I like the roofed forest biome a lot myself. It is an excellent wood resource, with some added atmosphere and added chance for daytime mobs. It can be a little laggy with the added effort put to the lighting, but that's barely even a nagging annoyance. I have noticed that with decent sized roofed forests, especially with large biomes turned on, you can still get sporadic clearings, which makes it even better if you don't want to have to clearcut to get a decent building constructed. Not to mention the potential for treehouses and mushroom houses.
Considering how roofed forests make me think of the Black Forest of Europe, I wouldn't mind if there was an increased chance for witches to spawn there.
