It's not the fact Dire shrines is a little lava basin which you can touch to recover yourself which bother me, I can deal with it being just a healing magic channeled by the ancient or something.

What bothers me is you can't refill your bottle there, even thou you can do it on your base fountain, and yet, putting glowing stones (read, runes) inside your bottle fills it with water.

I know, I know.. logic in videogames but c'mon, a shrine filled with water should work to fill your bottle! Maybe that was the original idea but Icefrog changed his mind for balance reasons.
