open topped and ."abilities"

hi to all.
i know this is a open issue about transport model..
the rules state that the models in transport cannot be affected by any "abilities"
in you gaming group how you play it?
i have many liquifier gun in ravager and venom..they hit automatically or is an ability?
can i use dark tecnomancer?
If not i can shot with a plasma in a marines land speeder and don't die on 1..
or i have not feel no pain (or equivalent) in embarked model..or any.."abilities"
in my research abilities are only auras or stratagem ..someone have a valid idea about transport and "ablities"? i lose even power from pain ..marine lose..all marine stuff ad are not still marines..i feel the wording is very..incomprensible O.o

The incremented abilities of your units are still valid (as for the abitlities of weapons).
Auras and Stratagem cannot target or affect anything inside a transport (yours or enemies) even if it is open top.....something i would really love to be changed in the next codex.
But yeah, inside an open top transport, your poison weapon will still be poison weapon, etc....
But you can't use the reroll aura of Archons for exemple nor a stratagem.
Hope this will help clarify
