Not really. The game is perfectly playable without EnderIO. Or without TE. I just feel that a choice in item transport mods is a good thing. Linking item transport to TE makes it a false choice and isn't good.Looks like that's exactly what Ender IO did.
When TD does release, it'll be a reasonable method of moving things about and it'll fit with existing stuff. Ducts in 1.6.4 were a bit too cheap and a bit too good. EIO basically copied the formula and raised the cost a bit. I want them to be a bit more interesting than that. EIO isn't my cup of tea, but it's a good mod.
