I really wouldn't pick feats for both 4th and 8th - Paladins are MAD, and ignoring your ASIs completely will leave you well behind. At 11th having only a +3 to hit/damage, +2 to HP for a somewhat tanky role, and missing out on some of your aura and Conquest saves with only a +3 CHR is well behind the curve.
If you want one of the styles from 4th, go for it but take +2 STR at 8th. If you want Resilient (CON) then take +2 STR at 4th, and rearrange your starting ability scores some to give you an odd CON so it boosts it. I'd suggest DEX 8 and CON 15. A DEX penalty won't hurt your AC in heavy armor.
Thanks for your advice!
Resilient (CON):
You are right. Furthermore, I think Resilient is stronger on
later levels, when the proficiency bonus that is added, is higher. I even might find out that there is no need for resilient, because the Aura of Protection (adding CHA mod. to all my saves) might be enough.
Dumping DEX:
If I see it right, dumping DEX doesn't make sense without Resilient, because there are no stats to put these points in, are there? In addition, I think DEX 10 is not the worst choice, because it's an important saving throw + gives a bonus initiative.
STR 15+1 | DEX 10 | CON 14 | WIS 10 | INT 8 | CHA 14+2
Feats:
Isn't it important to get a good use for my Bonus Action and Reaction? Polearm Master and Shield Master both offer good opportunities for that.
Polearm Master offers a Reaction attack + Bonus attack.
Shield Master offer Shove as a Bonus Action + Advantage for subsequent attacks.
If I see it right, this pretty much exceeds +1 STR mod, doesn't it?
Thanks in advance!
