You said your original idea was lanterns and you had to use oil to capture the lantern for vision. Why would you drop that for a much inferior idea? You could easily add top jungle, make oil 50-75 gold and make lanterns last 2 minutes. This would encourage strategic play and be a MUCH better idea. This keeps old TT in mind, but adding in the new stuff. This is better than 2 altars that promote snowballing and turtling more than anything on old TT.
