Been playing 4th a couple of times, and i see a great lot of potential in this edition!
Though, the rulebook is so crammed full of juicy info and bang for your buck, it has resulted a bit in some quite short descriptions of some of the rules, and i've got a few questions about some mechanics, i wanna hear your thoughts;
1) Strike to stun talent seems pretty good for a free chance of giving an opponent a Stunned condion + normal damage, AND ALSO have the chance to rack up double Advantage on your turn, AND forcing the enemy to spend their action doing an endurance test to recover, if they even succeed with their -10% per stunned condition. Then, the next turn, you StS again, gaining 2 Advantage becuase you already have 2 and the opponent has -10, PLUS and additional for attacking a stunned person, gaining 5 advantage on 2 turns, not counting in your defensive rolls. In 2ed, AP on your head would grant extra bonuses to resist the stun, but i cannot find any similar rules in 4th. Have i missed something, or are there no other drawbacks than having to use a Pummel weapon with StS?
2) About fighting larger opponents, it says that if your one step smaller than your oppenent, you get +10% to hit. When shooting a large opponent, you also get +20%. Does that mean, that a human would effectively always get at least +30% extra to hit large opponents? (and an additional +20% if point blank, racking it up to a crazy +50% BONUS).
3) Trappings: i know this system has been written for people who've already played Wfrp before. When advancing to a new level or tier or career, you had to have all the trappings of the new career in 2nd ed. And it seems like it too with the trappings listed in 4th, but i cannot find any rules describing trappings as a prerequisite for advancing. Have i missed something or did cubicle 7 overlook this one?
4) Do you gain advantage for every single opposed roll you win? Say you fight against 5 other people. They all attack you, but you took the defensive action gaining +20 to defend, and win the first two opposed attacks, and are already on +40, easily defeating the other opposes. In 1 round, you already raked up 5 Advantage, which could be enough to easily, singlehandedly deafeat all 5 opponents. Ofc, there is the outnumbering rule, but seems wild that the Advantage can rack up that fast when attacked by multiple enemies.
5) On Overcasting magic, it says that for every +2 SL you get, you may double an effect of the spell. But many spells already have a CN of 4, 6, 10 etc. So everytime you cast any of the real spells, you will always overcast it. Or does it have to be over the CN, in which case it seems pretty rare it will happen.
Can anyone who have had mages in their party or played one, tell if the mechanincs for casting spells and channeling was any fun? All my players rolled non magic users

Sorry for the wall of text!
The things lacking does no where near beat me down, as there were far more stuff that was missing in the 2ed. This version seems like so much fun.
