In one third edition campaign I'm dealing with a martial artist/armored puglisit with 250 hit points at lvl 14. She is a walking nightmare that hits like a truck and takes hits like a truck.

How?
How does a 14th level character have close to 20 hp's per level?
The difference is that earlier editions fighters and rogues could use their "powers" pretty much whenever they wanted to while wizards and clerics were limited in their "powers" to a few times per day. The martial classes had the ability exercise their chosen options more frequently.
Weapon specialization? You could use it in every combat. Want to specialize in mace too (per your example), take a feat at the next available level (which for fighters happens fairly quickly). Rogue who specialized in diplomacy and now needs to invest in disable device? Yep - next skill level add points. Or buy masterwork tools or magic items. The wizard and cleric were stuck with x amount of spell slots. Their options are their choice in spells and the ability to switch them out each day./snip
What? You didn't have wands, scrolls or potions in your game? Limited by slots? Not after about 9th level. What else does a wizard have to spend his money on? Heck, the cleric, after he's got some shiny armor, might as well bulk up on the same. Most of the really juicy spells are under 4th level anyway.
