I actually disagree. For one thing, even IF all possible WoE tactics had been figured out completely (I'd argue they have not due to the social tendency to accept that the current way is most effective until it is proven false), they haven't all been run through on heRO - thus making each WoE environment unique and adaptive - allowing for the very macro strategies you desire to be tested and implemented in each unique environment.
Example, when I joined heRO, no guilds used Lokis even if they had the numbers online for it. There was no tarot spam in the precast. The GT SinX line was not considered important (and often did not exist). Many things have changed on heRO and many things will change. There is more than one effective way to defend and, thus, more than one effective way to attack. But heRO prefers to stick to the status quo in general.
