Assessment of End Game Polearms

This is my assessment of an Aran's end game polearms:

Crimson Arcglaive: Fastest commonly available polearm, and decent base attack. Fairly expensive. Perfect for an average player and a SI bosser.
Maple Karstan: Same speed as an AG, but 17 attack weaker and a lower potential tier. Fairly cheap. Good for a low level player/ low funded player
Zedbug/Dragon Chielbird: The Dragon weapon is an upgrade of the zedbug, and they both have a slow (8) speed, making them really bad for an endgame aran, but sometimes used over a Karstan for the better potential.
Purple Surfboard: 3 less attack than an AG, but fast speed making it the best polearm for training and bossing. However it loses to an AG and RSB when there's SI. But 3 attack is not that important. Incredibly rare. Incredibly expensive.
Red Surfboard: A weapon with equal base attack to an AG, but less speed making it worse in all cases except for SI bossing, in which it is equal. Average cost. Decent damage. Cheap alternative to an AG.
Heavenly Messenger: This PA is rare, and it is 5 more attack than a Karstan, but shares its lower potential tier. Expensive, and not worth the 5 extra attack over a karstan.
Reverse/Timeless Disera: As expensive as an AG, (timeless is MORE expensive) and less damage output. Under SI, an AG still beats it. Plus, you can't trade it after its equipped. Higher leveled, but same pot tier. If you can afford/make this just get an AG.
Machlear: Often used in bosses due to its 5% extra crit rate. And skeles/O4/5 training for the damage bonus. Same speed and base att as an AG, however goes up to 20att less and must be scrolled with tablets, which can blow it up. Also it costs 5M/2hours to use, so it is not efficient to your wallet. Also with nerfed crit this is a ~2-5% increase to your damage. Not worth the extra effort to scroll over an arcglaive IMO
VIP Polearm: Slow speed, however it can destroy the arcglaive under the right conditions (with SI and Acc-E7), and better potential. Not as efficient for the average situation though.Fiarly rare and expensive. Discontinued item though. Will become more rare and more expensive with time.

Forthcoming Polearms:
LHC polearm: this is either the level 140 or 130 one. If its the level 130, the large dex required to get it is worth the Fast (5) speed. If its the level 140 polearm only, don't bother. Slow (8) speed at 122 attack is pretty much the VIP Polearm with a really high dex requirement. WHen it comes out 4th pot tier will be removed so it doesn't beat the arc in any way except in the best conditions, however under any other condition, the arc wins.
3rd tier Maple PA: Same as the AG, with 10 less attack and no DEX requirement. My advice: if you have the dex, get the AG, if not stick with the Maple PA. Since 80 dexs easy to get with all stat equips, the AG is likely better.
