Ars Magica 2 vs Ars Magica 5 weapons, armour and combat

[Yepesnopes]

Honestly, I have only read about these complains in another thread about "What would you change/add in a Ars Magica 6th edition".

What would you change in a 6th edition?

I'm curious what people here feel are the weak spots in 5th edition. Honestly, I hope there isn't a 6th edition, because I'm reading so many 5th edition books and I'd hate for that to go to waste! But I'm curious what people think the weaknesses of the ruleset are.
