The 5e ruleset works with levelcap of 20 per ability score. Going above that would break the balance of the system so I am strongly in support of the level cap.
Comparisons with pathfinder are not really that suitable as pathfinder has different set of rules and balancing around the saves and the ability scores.
Personally, I like both systems but they do not mix well.
why do you say that? There are a lot of items in the game that raise your abilities over 20.
I agree for a natural maximum of 20 + race modifier though. But i see no reason for the capped 15 at the beginning. higher stats cost more points, so for 1 really high score you would have to sacrifice points for others. Agreeable for me.
20 score plus race modifier at start? That is way overpowered and not really necessary. For a start 17 is fine as it is with the 5e system. One of the ideas of 5e was to remove/mitigate the need of minmaxing and alow for more balanced stat distribution. Furthermore, allowing such thing will require an overhaul of the enemies, companions and etc. IMHO there is often beauty in simplicity and that seems to be the case here.
No, 18+ race modifier at start. Othrwise it would stop beeing comparable to 3d6 system. So 20 beeing the maximum you can get at creation and 22 the absolute max (given a +2 mod).
Well, things like ability scores are more or less given at birth. You can train, learn and get expirience etc but normally never so much that you can double it up during your lifetime. So going for a high starting score seems reasonable enough. With some way to go higher.
Given the cost in a points system 15 to 17 2 points each, 17 to 18 3 points or something like that ( i don't know how 5 e handles it) you will end up with considerable deficit in your other stats if you go that way.
