Firstly, AFAIK, for many skills (fighting especially) the game takes into account multiple attributes in determining the characters effectiveness in that skill. I really like it that way, and it seems to me that this is asking for opinions on what single stat should determine effectiveness. If thats not the case and this is a survey to re-evaluate those multiple attributes, then ignore this disclaimer. But if skills are now getting one single attribute to define that skill... then see argument below.
language skills - int
baking -> dex
blacksmithing -> dex
carpentry -> dex
dying and tanning -> dex
fireing bricks -> dex
fishing -> dex
gemcutting -> dex
glass blowing -> dex
goldsmithing -> dex
herb lore -> dex
lumberjacking-> con
mining -> con
peasantry -> con
smithing ->dex
stealing ->dex
tailoring ->dex
library research -> int
Stealth -> agi
traps -> dex
concussion weapons -> str
distance weapons -> perc
dodge -> agi
parry -> dex
poisoning -> dex
puncture weapons -> dex
slashing weapons -> agi
tactics -> int
wrestling -> dex
alchemy -> Int
I'm indifferent about the dex argument, really....
though
If the staff decides ADD/REMOVE stats from fighting... AGAIN... players deserve another free stat change. It was BS enough that after about ~7 years of this game having absolutely no relation between int and fighting, they added int as a fighting stat (a very crucial one, at that). Now if after ~9 years of this game having a strong relation between dex and fighting... and they remove it, it's only fair that fighter chars are given another chance to edit their stats accordingly.
How the staff changes the definitions of stats really hurts older chars like mine. When i made Salathe after the wipe, the staff refused to tell the playerbase anything about what attributes did. We were all told to find out ingame. The problem with that is, that after about 5 months when we actually have experienced this complete remake of a game, we find out such things like... dex is very crucial for crafting, which hurt some crafters, and etc etc. And after those 5 months, no one wants to remake their char. And for those characters that have been around since the wipe, can see how much changing of stats has hurt Salathe as a fighter.
Cassandra gave characters the chance for a very hefty stat change when the argument of stats and RP came into play. This was used by a large amount of players (fighters and mages alike) since some mage characters had been around for years, but were hindered now because the mage system was brand new and how could these characters have any idea how to make their character 2 years beforehand. And of course fighters used this. Fighters did not use int much at all before this, and we all soon found out that int had gone from 100% worthless to one of (if not the most) important fighting attribute. It's a good thing Cassandra did allow players to accordingly change their stats, a lot of flame and bitch topics would have popped up fighting against what had happened.
I'd go as far to say, i'd like to see the system many mainstream games have. Every time a technical aspect is changed, players are told what is changed, and given complete explanation. Also, the players are given the chance to change whatever points they are able to distribute that are related to the change in that aspect of the game. Though... i know this wont ever happen in Illarion
SUMMING UP, all i'm saying is that if a stat is being removed (or added) from an entire aspect of this game, players deserve the chance to edit their characters accordingly.

The change in terms of fighter ability to craft stuff for themselves would be.. zero, right?
