I feel like College of Swords bard is a natural compliment to Wyll. He has fantastic stats across the board which is what a Bard needs and strength being his only weakness is mitigated by Pact of the Blade(?) Warlock using his charisma modifier for attack and damage rolls. He was originally a bit of a braggart in EA and that's kinda how I still remember him. Think the bard fits him personality-wise based on that and he comes off as a bit of a charmer as well.
