What is the absolute best opener for summoner?

[Seaku]

Xpot -> RS -> Bio2 (during tank run in) -> Miasma -> Bio -> Contagion (spam this just before bio) -> Fester (while running in) -> Miasma 2 (while right clicking boss for auto attack) - > SC (ogcd) -> SF -> Rouse (ogcd) -> Ruin 2 -> Spur (ogcd) -> Ruin 2 -> Fester (Rs should have have 1 sec left)

This seems fine for the most part except for the Misama II AFTER contagion. What's the point? Miasma 2 does 75 potency when not contagioned so is less than a ruin or ruin 2. It only does more damage than ruin with contagion adding on 50 more potency to make it 125 potency. You might as well replace miasma 2 with ruin 2 in your rotation, or change the contagion to after miasma 2 not before it.

Edit:

Miasma II for me is not worth UNLESS you fight 3 mobs +

MP consumption make its worthless if only 1-2 mobs there EVEN CONTAGION ON

and its not DPS increase at all, believe it or not

Yes because with contagion 125 potency is less than 80 potency of ruin, so yea it's totally not a dps increase. /sarcasm

Whether it's worth the mana for a small dps increase every minute is up to you really but it does increase your dps ever so slightly every time you contagion it. Over the course of a 10 minute fight it puts you 450 potency ahead of someone using ruin in its place.

Ah thank you for pointing it out! I guess you could slot in M2 after contagion then. xpot with RS with contagion M2 should do more than a R2 I think?
