Agree..
Since wpf started to get taxed/capped so aggressively we don't have the 200+ wpf agi chars anymore. My most fun char was my 10 Athletics Jarid-throwing superfast Ninja at lvl40.. Of course that wasn't fair for new players.
Nowadays, heavy STR-builds frequently one-shot me, and people in much heavier armor, with greatswords.. It feels a bit like being cheated. IMO it should be balanced so you could take at least 1 hit before you go down in most cases. I would accept it for the heaviest and most unwieldy weapons, but not for all-rounders like greatswords.
I'm also for softening the wpf penalty at higher levels a little bit, or make the curve a bit flatter. (Too much would require rebalancing of everything once again)
Anyway, I would say AGI is still more fun to play, as you get many more tactical options rather than jogging to the battle and start spamming.
* Diggles - No, having str-requirements is very important to not let agi-chars get the flambies i.ex. Long, extremely powerful weapon + much more wpf is deadly, and perhaps unbalanced. But having STR-requirements, when STR is currently the most powerful choice defeats the point. Buff agi pls!
edit - Also want to say that the weight influence on running speed needs to be leveled a bit higher. Now your athletics gets eaten up almost entirely if you have as much as 12-15 weight. I thought the idea of it was to get the tanks, not everyone not in a T-shirt.
