Just wanted to offer a few thoughts, my main was a PDK 18 Bard/1 Fighter/1 Cleric for a while and I think they make for a solid solo build as well as melee dps and raid buffer.
#1. Warchanter bards have the potential to be moderately tanky thanks to Core 4 temp HP, Uncanny Dodge from Swashbuckler, and self-cast displace and heals.
#2. Reapers cannot be frozen but I usually use Otto Irresistible Dance + Quicken. But IMO most mobs can be frozen including many constructs and undead which resist a number of other forms of CC.
#3. Playing as PDK with Cormyrian Knight Training makes freeze DCs incredibly high (into the 120s on a high investment toon), my CC was landing reliably.
Quick note that a lot of the items from the upcoming raid look fantastic for melee bards.

If you're flexible on race I'd recommend 3 different options:
1) PDK as mentioned above. (If you don't mind the doofy look).
2) Aasimar Scourge on a toon with many racial AP using light mace (like Mori's Focus from the upcoming raid).
Disgusting crit profile: 15-18 x4, 19-20 x7
While dated, Fivetigers33 R10 bard build still has a lot to offer for insight into high end bard play.

3) Shadar-Kai, given a bard build using a light melee weapon, the new chains attack is fantastic.
Happy to flesh out any of the build ideas above or offer ED/gear suggestions.
