iRO and other low rates...we here at fRO don't play like iRO - if we did, we wouldn't have to rely much on yggdrasil berries, or even healing items since the damage output and furthermore DPS wouldn't be high or overwhelming.
With the increased availability of yggdrasil seeds, and EDP bottles - and the sharp increases in attack bonuses due to the hightened stats, custom weapons, and availability of such cards as incantation samurai and turtle general, there is an large emphasis on damage output. Assassins are capable of lightening speed DPS with their basically unlimited supply of EDP bottles, and Champs can ygg frequently and spam Asura with kiel cards.
Following along so far? Good.
Yggs are so necessary here - it doesn't matter how much strategy you use, you get caught by one asura or even one second of an assassin cross on dual daggars or even two lord knight bowling bashes, what is the first thing you do?
You don't click somewhere else to move and re-strategize.
You ygg.
And in the case of the assassin cross, you burn through 20 yggs.
If this was iRO, you wouldn't need to ygg or use healing items as rapidly as we do here on a high rate server like fRO since priests would be capable of outhealing and skill delays would slow down damage output for you to even possibly, run, recover, and strike.
So it's fine that certain classes that aren't strength bases don't need an increased weight capacity since its not necessary for good players to carry healing items. But in fRO, priests can't outheal the DPS, so healing is up to the player.
Every class should have an equal amount of ygg capacity, and so far, through the most recent update, a lot of them do. Stalkers can get away with 70-ish str and carry 200 yggs. That's crazy for a class that is able to hide, stealth walk, and backslide to avoid a lot of damage.
Gypsies/Clowns on the other hand will carry somewhere from 80-100 yggs, less if they want more armors or aren't elite, won't have the ability of backsliding away to quickly get out of a scary situation, and they don't have pushback techniques like LKs, and Paladins have - or even Wizards with storm gust. All they can do is slow grace (if they have soul link as a clown), speed pot and run away, but they'll still suffer a lot of damage while making the getaway.
You can argue that tarot is great, but against FCP'd GTB'd character's, coma doesn't do the trick like you want it to. You say, "Well then AV their asses!". It's not that easy to pull off 3 AVs in one run, the usual is 2. And they can ygg before the third one hits. If you had a thana card, then yeah, you could toast a lot of players - until they put on skolls.
In my experiences in LMS, it's a game of outlasting their FCP. And to do that you need yggs. It all comes down to that, sadly. There are other factors like equips, and general skill, but you can't deny that yggs play a huge part in gameplay for this server.
