teleportation is pretty energy-consuming in reality
Please tell me of this technology you have discovered...it would be handy.
OT:
To be honest, I completely disagree. Teleporters are not designed for hopping floors, going between villages and houses, and skipping out to the nearest attraction. They are designed for distances even the nether cannot comprehend fully.
Need to get to another floor? Use stairs/ladders
Need to get to another house? Walk
Need to get to another village? Minecarts
Need to get to another part of the map? Nether
Need to go to the fucking moon and back place really really far away? Teleporters
Each method of transportation is designed for a specific range, and they work well when in that range. If you expect teleporters to use your idea, you destroy their only advantage over these other methods of transportation, which is massive transport range with minimum cost.
Lets think of it this way. Would you design a massive minecart station in order to transport yourself to the next room? Obviously not, because its excessive and unneeded, you can just walk there easier. This is because each level of transportation has a certain worth for distance. You wouldn't use nether portals to go around a village, but they are great for going between villages. As the distance scales up, the inaccuracy increases, so you must combine different levels of transportation to get to where you want. IC is designed to be a supplemental mod, it is supposed to take what MC already has and improve and increase upon it, and this is exactly what the teleporter does. It is designed to supplement the current transportation to allow for even farther ranges easier, not to overwrite every single transportation system in the entire game.
TL;DR: No. It should actually be increased.
