suggestion 1-4 person crafting dungeons

i personally love pushing the idea of mmos further and with games such as the last of us and tomb raider really brings up the idea of why cant we push the standard staple of crafting to the next level other then gather x mat craft x item why cant we use crafting in dungeons as a means to actually run and complete dungeons chopping vines to seek past enemies or dropping tree branches on to a group of enemies crushing them making bandages to heal our friends repairing battering rams or fixing up turrets catapults ext the ideas of bosses being taken down with nothing more then crafting professions would be amazing good fun let us use our heads and think up strategies for what is in our party have the mining and botany classes fill the tank spot weavers and alchemists can fill healer spot will the rest of the crafting classes can fill the dps slot it would give people an alternative to level crafting other then running around gathering and crafting and doing lev quests or gc supply missions and really show squares ability to think outside the box and really give all the crafting classes some exclusive content that they really deserve since they really haven't got a lot of content for them to do not to mention as a fan of ff tactics and the old turn based combat of past ff titles mindlessly pressing 1-4 with a dodge here and there gets old fast being able to actually think and come up with a strategy would add an amazing level of difficulty to the game since you wouldn't always get the same type of make up each time and would have to figure out how to complete each boss let alone the trash between bosses with the group you have
