As to what concerns the most deadly builts out...

5 minutes. Probably less actually, but that's about the length of time it took for a zero-danger multi-kill environment to remind me why swore off Bow 'Zon s in the first place. She had a sleep inducing lack of fun factor.

While the Bow using Amazon has argueably the most potential to be "abused" as a cooky cutter, this is only true for those playing within a very limited area of the game using only a limited number of approaches.

Easy part: the combination of doing physical damage (or more precise: damage one can leech mana and life from) without having to stand up face to face with the monsters is obviously the strong point of Bow using Amazons.

Weak part: many areas in the game do not favour amazons (mainly tight ones with lots of corners) single, strong, hard hitting monsters can be easy and quick death to (unskilled) amazons

I can clearly understand the general outcry about how overpowered Bow using Amazons are. They surpass most other builds in killing speed in the popular cheap-trick exp areas.
What most people forget is that it actualy takes skill to finish the full game. (In contrast to getting "rushed" past any possibly difficult part to get to Hell Cowgames where even an unskilled player can wreak havoc easily) So before putting the Bow using Amazon in the "boring" category, take an above average equiped "Bowazon" just do the quests...
Multishot one trick ponys won't cut it! A multi-skill (Strafe, Freezing Arrow, Immolation, Guided Arrow, Decoy, Slow Missile and yes, in some situations even the "Cookie-Cutter-Signature-Skill" Multishot)

Judging the fun of a whole class by the ease of clearing the foothills and the cow level with one skill sounds a lot like a predjudice to me.

C-C-S-Ss may make easy Characters for certain Situations, but if you let them break your enjoyment of a whole class it's your loss.
