Seeing as you haven't played the class it's hard to take what you say seriously but I will counter anyway, veelas were sup par before the patch and are now the worst race for every class because the speed is negligible.
You say just drop some str/con/dex to get the extra int further gimp already lower performing aspects.
What some players are saying is just plain wrong, 50 int never meant same output as 120int.
Having an output cap at around 50 meant that some classes could utilise some spells even though they could only use it a couple times, for example an average veela hybrid didn't even have enough mana to kill someone with magic unless they gimp other stat's, so they were never operating as a "120int" mage for 50 int like some short sighted morons are continually spouting.
Hopefully you will go ahead with your test I look forward to the outcome.
Yeah I mean to achieve 79 int on a fighter based Veela you'd be min height and drop 4 points of strength, if mortal data can still be believed there is no difference between 70 str and 80 str other than 3% DB, same hp, same stam. This would make sense, if you look at Dex you see the biggest change around 70 then it starts to taper off again. Not sure exactly how Str curve works, would be interesting to see.
In any case I'm told 100 is the new 50 for magic meaning if your average heal was 23hp then it should be around 18.17 now (if int is 79), if greater is like say 45 then it should be around 36 ect. 5hp to 9hp heal difference and 4-5% damage bonus difference is a nerf, those points do add up absolutely and when you consider your mana (which you will have more of now) restrictions I can understand the argument for a curve around 50 and up to a degree being in place. Id like to see a graph displaing, I'm not 100% on those numbers, just going off the 100 is the new 50 for int comment i've been told.
If you went pre patch and put 80/90 into int can you still tell me you wouldn't have enough mana to kill a player ? Either way I think of most things in a group format, 1v1 needs to be considred but its how its going to scale in a group that is the bigger issue.
I'm reinstalling MO now, will take a few notes on my Thursar stam and speed and compare it to the stam and speed of a Veela and have a few fights to see how the speed feels. Imo if the speed is a factor that can be utilized I believe Alv clade needs to be kept in a very particular place. The potential for it to be the only viable class is very high if you empower its speed too much. When you think of the fight in litreally any other terrain then an open field if effective stam is competitive with other clades then their speed and clade gifs give them the upper hand as a hybrid or bow/fighter.
I don't have all the answers, and I absolutely need to try it out personally and look at some numbers before I'm willing to say "yeah its fine people are complaining because they want their fav calde to be to strong" I can understand why a curve might make more sense.
