After Hours of trying I completed 3 Seraph Tower Events
I hope my contribution was enough because it took so long to finally be matched with 4-5 guardians. After we beat it 3 times they all left and I am now 1 short on my weekly bounty :(
Personally, I think Seraph Towers can be fun under the right circumstance, I mean they are no different then Court of Oryx or Archon's Forge which I enjoyed. It seems the community is extremely frustrated over the lack of content for the past 6 months and perhaps that is why it is so hard to find people in these events. Either way, the Seraph Towers is a cool activity, I just wish I could actually play it as intended and not constantly waiting for more people to load into my session.
