With rens becoming a tad obscene in time taken (never mind sorting out a new hero) is there any light at the end of the tunnel in future patches?
= Do we get a 4th trg ground or anything to help?? It was level 120 or so when we last got a faster trg speed!
chinese servers have "hero training" activity that provides 20% boost exp during the activity (kind of like levy activity used to) and the enhanced training costs are reduced.
Unfortunately in our current version we don't have anything beyond the 3 TG's, trainers to train and transcendence or laurels to fast track heros. My suggestion is since the later stages hero training is time consuming and even more expensive than it was at say level 120, slow down the map progression in order to allow the stock of transcendence which will speed up the hero training. If it is broken down by how long it takes to get the trans to FT it's actually faster stocking a bunch and then running sets of 99 per hero.
It is the best options until something is added to the game that will help with hero training.
This is my opinion based on some of my own trial and error. I hope this helps
