I was wondering:)
do you still level up slower after you pass the lvl 50 mark (need to up more skills in order to level up) ? or has the lvl 50 soft level cap been removed? also: do enemies cap as the same level as before or do they level up with you if you decide to reach fx. lvl 100?
cheers:)

From what I understand, the level cap has been removed. Or I think its been changed to 100, not sure which. I know that when a perk tree is filled, you have the option to make that skill a legendary skill, which takes away all the perks for that skill and sets the skill level down to 15. I also understand you get the points back from that perk tree and you can use them for something else, and then you can re-level the lowered skill back up to 100 again. I could be wrong on some aspects of it, but this is currently how I understand it to be. I think its great because you don't really lose anything, and you can effectively keep leveling forever this way.

Well basically, there is no level cap no more, meaning you can level yourself as long as you feel like it... Most enemies (should) still stop scaling at 50. The way you keep leveling is, as mentioned above, by making any skill you have at lvl 100 "Legendary". By making a skill legendary, its level is returned to 15, all perks invested in that skill's perk tree will be removed and the perk points will be returned to you, so you can either use them on other perk's or save them to replace them in the same skilltree once you level it again. (youll still get more perk points by getting more overall levels, too, as you do normally)

As for if the leveling is slower, the usual leveling up process applies here - you get overall xp by leveling up your skills. The lower your skill levelup, the lower overall xp you get (meaning you get less overall xp from leveling a skill from 15 to 16 than to, for example, 80 to 81) but, the higher your overall level, the more xp is needed for next lvl.

Thats as detailed as i can get

That's generally right. As for the extra detail:

(Current Lvl. +3) x 25 = exp. needed for next Lvl.

yeah i said the higher your overall level the more xp is needed, i wasnt planning into going into mathematics just to keep things simpler
