In earlier versions of the game, dropping and igniting a candle was not an action, I did not test it in patch 7.
Any items movement between game enviroment and inventory is still completely free.
Personaly i have no problem with torches ... they seem to me like lazytrap, just as everburning blade is ...
They seem strong, and they even are first few dozen minues is game ...
But once you get your hands on litteraly anything else (except Daggers) you have stronger weapons, for the cost of single Bonus Action (wich can easily be avoided with certain artefacts later.
The only problem that was known with Torches was that they could be also poisoned ... i didnt try that yet in patch 7, but i hope that was allready fixed.
