First of all thanks for your hard work into making such a list. Cenre already mentioned the flaws in the list so I won't mention that again but I will offer a possible solution.
My suggestion is that you simply consider, how useful a specific class is in the current metagame (Sun Temple) instead of seperating classes into Tank/Dps/Buff/Heal:
For example a D/S is a great healer but offers less support than D/Wd, D/W or D/R. These days a healer should somehow support the group and unless you need Group Exorcism (which is not the case for Sun Temple) there is no reason to use D/S these days. This makes D/S a pretty useless class unfort. -> Bottom
Scouts with W, Wd and R as secclass should all be Godtier. While S/Wd is probably the strongest unless there are lots of Vampire Arrows for S/R, all of them offer a huge supportdebuff. Compare this with a Ch/R who also has a solid burst and very strong offburst but just offers 0 support for the group. That is why I think considering Ch/R as "Top" is appropriate.
W/M might have a slightly better sustain than Ch/R but its burst is def. worse. However, they can support a potential group of W/S or W/Wd with Probing Attack, allowing them to spam Open Flank. They still are not really good in Burst which is the focus in Sun Temple -> "Top" Tier. If they did not have Probing Atk I might have suggested "Mid" tier considering the burst nature of Sun Temple.
Wd/M is considered Trash in your List. While you admit that you did not play most of these classes, it is true that Wd/M is rarely used. However, it is a fact that a Wd/M can almost do the same dmg as Wd/W. So why use Wd/M over Wd/W if it is slightly worse? Because Wd/M is actually much better in sustain. The Pets damageoutput is actually insane if you summon it with high p.atk and p.dmg and give it all the buffs it needs. The problem is it takes time to ask for p.atk and p.dmg increasing skills to summon the Pet for high dmg which might be kinda annoying if it happens too often (basicly if your Pet dies or you fail to kill the boss and change Zones). That is why I would consider this class as "God" Tier. It can still support the group with the Pets debuff 6% more physical damage received.
W/Wd has 100% a worse burst than Wd/W but a better sustain because of its natural higher p.dmg with 70% over 50% damage on twohanded weapons. Even if you see W/Wd and Wd/W doing the same damage, do not forget that a Wd/Ws Pet does damage as well. Up to 20kk in short burstfights, if you summon it very strong. W/Wd is very strong, if the Boss have super high defense. While lower defense on Boss makes everyone stronger, low atk Classes profit much more from this compared to high atk Classes. However, I think that a W/Wds worth in a group is better than a Ch/R because of the 5% dmgbuff for the group and since Ch/R is Toptier, W/Wd should be God Tier.
Wd/S should also be God Tier. While their damage is not their strongest distinction, their support makes up for it. If you consider your dmg as Wd/S + the damage done by the group without your Dmgboostinf buff, it should be higher than most of the classes in the Group. It can also support a S/R with Vampire Arrows and has a pretty good sustain with permament 25% Atkspeed from its Pet.
Wl/Ch actually has a usable burst and a very strong sustain. This is due to the fact that this class gains very little from typical Buffs such as Music or Castspeedreducing Skills compared to other classes. Their darkdamage increasing skills have very short cooldown. They can also resurrect in combat state which can be a crucial skill. Considering this I would def. put them in Top Tier.
K/M has a stronger burst than W/M in Suntemple, if K/W in your group uses Punishment which increases Lightdamage received by 26%. However, they offer no support other than maybe Tank Shield for B3 in Suntemple if you do not use your 5min cooldowns or their speedboosting Groupbuff. -> Top Tier.
macht aber Laune.
