It already is easy to get max damage reduction, the only difference is that without greater DR ber rune you have to use the same set up on every character because otherwise youre using comparatively weaker items.
If cost is a gauge, then utilizing bers with higher DR would make it more costly/harder because then instead of using say, a cheap verdungo, and stormshield, you can use stormshield with a ber rune in it ( that costs more in alot of cases).
Most items that could be alternatives, even combined with Max DR from upped bers, would not fully compare to the main cookie-cutter set ups, but the point is to have some different options instead of being relegated into using boring cookie-cutter gear that requires no thought to select.
For example,
Vampire gaze does not offer much beyond DR vs. a cookie-cutter COA with similar DR potential (more than Vamp Gaze), +all res and + to skills
Mosers Blessed Circle does not offer much in comparison vs. Stormshield, if socketing with Ber Runes for DR. It provides less /similar in all stats, but 2 additional mediocre resistances ( at the expense of higher individual (cold) resist.
However, these could be utilized as effective alternatives if you could gain increased DR via ber runes. Both primarily for graphical alternatives.
Upped Ber Shaftstop / Leviathan could bring a player to near max DR, opening the slot for a high resistance shield, vs using high resistance chains of honor body armor with stormshield, despite shaftstop / leviathan not comparing in other stats to all that chains of honor provides. To finalize the remaining DR you could utilize any number of helmets, with DR already built in, such as shako (cookie-cutter) or rockstopper, or ber’d alternatives.
with upped 15dr bers
Cookie cutter - Chain of hour ( 65 all res 15DR ) + Crown of ages ( 20-30 all res 30DR ) = 85 to 95 all res + 3 skills, 50 (Max) DR
Non Cookie Cutter Alternative - Ber Leviathan (35-40DR) + Sanctuary Shield (50-70 All Res) + Ber Veil of Steel (15 DR / 50 all res ) = 50 (max) DR, 100-120 all res, + No Skills
Comparative DR, Comparative Res , Sacrificed + skills, changed graphical appearance ( also note, cookie cutter option still has slot for a shield not designated )
Greater DR Ber could even open up the usefullness of Rares, such as
Rare Armor with
24 FHR
60 Life
High Defense
Eth Repair or Resistance

30% Damage Reduce (Ber Ber )
