I think the issue here is that people expect the modders to code specifically for a mod pack and not for their standalone. While this is a legitimate gripe in that a modpack should intergrate mods together not just be a compilation, its the same argument as multiple power types. There's still no unification there, yet there's not a huge complaint system, so I don't get why there's so much focus on a tool. I think the real issue is that people dislike the IC2 meta game aspect.
I'm fine with how IC2 tools work as it makes you respect the machines and the underlying power system, while putting in a sensible progression hurdle that directs the gamer to the proper support systems before the big machines (base load power and wearable storage before nuclear reactors). I also think powered tools for complex machines make sense, and that the omnitool is stupid cheap for how good it is. While I think a proper middle ground would be a powered omnitool, I realize this would hurt mods like forestry so its not viable, and two omnitools kinda defeats the purpose.
Since the above is kind of unresolveable/is already resolved via the omnitools update, here's a good question for discussion that really is the root of it all: do you like the tool meta game or not (durability, tool requirements, etc). I predict the answer percentages would be in line with the above poll.
