>I have no idea how high 110 HP is comparitively to the rest of the game
By default a level 5 Barbarian has 40HP and they're both the highest class in terms of starting HP (12) and per-level increase (7). This is not including their CON bonus modifier, so if the said Barb has 16 CON that's +3 extra HP per level (total at LVL5: 52HP). Flind and his pack of gnolls often cited as the toughest early-game fight as most players encounter them at LVL3 at most. The problem with the Warlord outside of his bulky HP and decent AC is that his Saving Throws are high in 3 (out of 6 - with no negative modifiers at any!) abilities and has an insane +8 Initiative for some reason.
For comparison the end of Act1 has multiple mini-bosses, one of them is the Bulette that comes with 162HP on Tactician and has +1AC on Flind but worse "minimum" Saving Throws. Another one, the famed Spectator has 153HP but all over worse modifiers and -3 AC. Hell, probably the Minotaurs are the most comparable to him but even if their HP is a little higher (117HP) they're basically Flind Light Editions in all other areas. Not to mention they're "only" level 4 compared to the rest (who are all 5 by default). And their Initiative are nowhere near Flind's and they don't carry a unique Mace +2. Again they're all located at the last quarter of Act 1, that players often called as "Act 1.5" for a reason.
So I know nothing about the mods but Flind will wreck some shit by himself. Very minor spoiler: you can reach Act2 from two late-Act1 regions, but nothing prevents you from completing both to maximize XP and loot. I've done almost everything the Act has to offer and close to the last 10% of it content-wise and I'm still "only" halfway to level 7. Most players reach the said regions and travel to Act2 at level 5 or so. This was clearly what the devs' expected and they designed this locations accordingly.
