Yes they can get those skills, Chanters can get skills to up their accuracy like Weapon Focus too. It isn't a question of "are these talents worth pursuing" it is a question of "how far am I willing to go to make a class that is not well suited for what I want them to do be capable of doing what I want them to do". A Priest will never be as good a tank/melee fighter as a Paladin or even a Chanter if you give them the same or similar skills as the Priest. Why? Because they have better base stats to support that role from ground zero. Just like the Paladin will never be as good as a Priest as a straight caster if you give them the sames talents/skills because the Priest was better at it to begin with.
I understand you want to be a priest. I am just letting you know a Goldpact Paladin is basically a 100% match with no need for tweaking on what you said you wanted to play. An off tank melee fighter with casting abilites, buffs, and a look out for number one attitude. You literally described a Goldpact Paladin in your OP.
Understood.
The way you said it made me think that no matter how much I tried, making a front-line Priest would be a bad idea lol.
Just wanted to make sure their talents didn't get ripped to shreds via nerfs; I know the wikia has a lot of out-dated information.
But yeah, I agree that Paladin, Goldpact Knight in particular, would provide me with the gist of what I want and with much less sacrifice.
Thing is though, having Dual-Classed from Priest of Talos at lvl 15 to Fighter in Baldur's Gate II and ToB, I am very used to sacrifice.
As always, thank you for your feedback; I appreciate it!
