So for anyone who doesnt know P1999 is old school Everquest, up through the Velious Expansion. It is allowed to exist by Daybreak Games and is basically privately ran, and designed to keeping that experience intact. Yes it is super dated and old, but it runs well. It is free to play. Downloading and setting it up is easy.
Now in old school Everquest your group was Tank. Healer. Support. Puller. DPS. DPS. The support classes did Some DPS. Buffed the Group. DE buffed enemies, CC’d. Support Classes, you had Bard, Shaman, Enchanter. To some extent Druid could be Healer or DPS. A puller was usually monk, or Bard or Rogue. Sometimes the tank.
Now content consisted of going to a dangerous place, finding a group and just grinding mobs in a group. Soloing is either inefficient or if you hyper optimize, very efficient, but only some classes can do it well.
The games by no means parallel. The encounters are super basic with little to no mechanics. Aside from let tank get aggro. Then start to DPS when you know you wont rip threat. But the support roles contribute some DPS, while providing great utility to the group. They feel like support classes. You notice when they are there and doing their thing well.
Augmentation Evokers are not there yet. And in the game that WoW has become, while a support role sounds fantastic to me, its going to be extremally difficult to do. The game was not designed with a support role in mind. And the way people play the game, many pigeon hole themselves into what the perceived meta is. And at the top end, you play meta or you are just plainly not as capable. And for a support spec to be good enough for the average player, it will end up being too good for the top end players. Which then will feed into the average players thinking its 100% necessary to have one.
In my opinion, the only real way to add support to the M+ group is to first decide what aspect their support is to bring. In EQ they would haste the group, slow the enemy’s attack speed, and provide some group buff. Mana/HP regen, staf buffs ect. The support spec needs to have a clearly defined role and purpose. Right now, they just buff the groups stats for the most part. Their utility is also brought by many DPS specs. Then I would suggest, once their role in the group is more defined add in another 4 to 5 support specs. Then Increase the 5man group to 6. Break the Trinity and have the group setup be build around 1 Tank, 1 Heal, 1 Support and 3 DPS.
Otherwise the support specs will either be too strong of a DPS boost to the group to be overpowered. Or be a watered down DPS that doesnt really do anything extremely well.
