Well, there is the 'brute force' rule under Athletics skill. That seems to take care of one of the more common uses of the Resistance Table. Look also at the 'Inanimate objects' table on page 93. The modifiers are interesting. I guess if you want to push a boulder down on some enemies, you roll STR+SIZ or less and you can push that generic boulder off the cliff... I think with MRQ the GM's judgement calls are to replace some of the game constructs from such as RQ2.
Not really, since it only affects a base %. Sort of pointless once you have a 80% Atlehtics to start it all over again.
IMO what the game needs is to give peole an amount that they can lift, moce, etc based upon STR or STR+SIZ. Something based on the old RQ3/ or a brand new SIZ/mass chart.
FOr example, in RQ3 SIZ 10 was 130-142 lbs, while SIZ 15 was 202-219 lbs.
SO we could say that a STR 10 character could lift up to 142 lbs automatically, and twice that with an atletics roll. A STR 15 character could lift 219 lbs for free, or twice that with an athletics roll.
THat sort of system would mantian the mechanics of the new system while still making STR important.
You could even have the skill score add in to the total weight when it goes over 100.
BTW, For those who want it, the low end mass for a given SIZ in RQ3 was roughtly SIZ^(sqrt 2)x2 , in kilograms. It wouldn't be difficult to put Carry Capacity on the character sheet and use this number.
