well i understand the uses in asura-cide, but i value that accessory spot for better damage output on my asura... but perhaps it does save you some blue pots / ygg seeds or berries... personally i would still go with monk combo set or morpheus accs...
autocasting is great, i have a sage just for that. BUT for high agi low dex sages, it's better to just use dagger of counter (for the constant damage output while the autocast part is for the extra damage) or get a sage's diary and put cecil damon and garm baby. Marina, savage bebe, metaller, magnolia, etc needs to hit to get it's effect while garm baby doesn't. And for the sake of autocasting itself, 2x Cecil = Doppel anyway...
Well perhaps high dex and/or high agi chars (hunters, snipers, sins, knights, etc) who deems it necessary to have a status weapon (usually 4-slotted) would like to have doppel-marina-savage bebe-metaller as opposed to cecil-marina-savage bebe-metaller due to the HIT penalty, but still it's uses are limited...
Bottomline is: it's not effective -in terms of marginal utility per pay- so perhaps SHRs can enjoy these cards aplenty but definitely not LRs...
again, the no-resetter problem is usually reserved for LRs and then in LRs the best way to level a DD sin would still be to use Katars first because DDs are equipment-intensive (read: costly) and i don't think it's wise to make a DD sin for PVM -> DDs shine most as breakers IMHO. So carding a drake card to a MG[4] would be the last thing a DD should do because DDs should utilize all the slots to maximize it's damage potential to break the emp and in most cases emps are small anyway...
