I'm looking at dodgemaster trait... It grants guaranteed dodge, but once per monster only. So, against burst fire enemies (commando, captain, arachnotrons) it has very little use.
Vs knight, baron, imp, caco you have 50 base dodge + 30 from HR2 + 10 from tactical boots = 90%
Sergeants, Mancubus, Revenants, Archviles don't care about dodging at all.
Former humans have 10 base dodgerate and low rof, so dodgemaster helps a lot to avoid their damage. But they rarely matter anyway. Cyberdemon has 30, and dodgemaster helps a lot, though with tactical boots and armor you have 80% dodge chance, and if you are running (extra 20%) - 95% chance.
Also, after 10th (edit - 12th) level you can get HR3, that raises dodge chance even against Cybie to 95% with boots.
So, outside very specific situations (like, AoPC) Dodgemaster is not worth taking. If you want better dodge, wait for level 10 (edit - 12) and take HR3 - it will let you dodge near-perfectly.
