Only time I've PVA'd a wall before tiling is if it is lime plaster
and in poor condition - to give it some more strength. I'd say the
most absorbent wall would be bare plasterboard - and not had any
problems tiling direct to that using a decent ready mix.

I get a surprising amount of 'a few of my tiles have fallen off'
jobs.

Probably through using a cheap/unsuitable adhesive. I had that when
using a Wicks one.

I never know what adhesive has been used, but its always the adhesive
has firmly stuck to the tile but not the wall, so I assume its due to
lack of PVA.

Suppose if the grout had failed and water got in that's where it would
give way first, since tiles don't usually absorb water. But I'm not sure
PVA would help in that case since it's not waterproof either.
