Thanks for the assistance on all of this, guys; been more helpful than you might think.
Talked a bit with the Rogue player; he actually admitted that he was wanting to run an archer build for this campaign as well, because... well, stealth archer. So, I think he's going to end up being the designated archer for this campaign, at least. To reiterate, we've got the aforementioned bow Rogue, a GOO Warlock, a Paladin, and a Knowledge Cleric NPC. I was basically wanting to make a character who could help cover any potential issues with the party.
Problem is, we seem to have everything covered already; Arcane, Ranged, Holy, Healing, Melee, basically got it all. Hence, I'm not sure what to really try to run; I brought up Swords Bard earlier because I had the idea to "roleplay" somewhat as a solo mercenary that got involved due to needing money, but given how weak the class is, I'll scratch going Sword Bard, at least.
Artificer sounds like a fun class, at least; I'll talk a bit with my DM, see what we can come up with. Thanks for the help guys; I admit, out of the 8 (rotating) players in my DND group, I'm the player that can never decide what to play on - can't ever find a main, usually just plays whatever. So, any help is appreciated.
