Don’t worry, I’m a fellow Oracle and I’m shooting down your line because of improbability. I refuse to accept that “people can access them generally”.
We are a mere handful at this point that have actually invested in Oracle; let alone C2 Oracle. I personally have a C1 Oracle at Lv275 (just a few more cards and grind and it will hit 280) and the aforementioned 225 C2 Oracle. Practically speaking, a lot of people have yet to reach their FIRST Lv280; add to that the “Alt-Fever” (w/c I caught as well) that the game promotes and this is where our point of view differs.
On topic though, I believe that no one can really make a “SOLID” decision if simply basing on what’s currently available (via teasers). They need the figures, the hard facts, the numbers to make their calculated choice.
On the other hand, anyone who’s fully set on making an Oracle C3, come hell or high water, will definitely be one of the people we’ll see selling GC in town.
We can all just hope for the best and just keep enjoying the game.
TL;DR: C3 Oracle feels meh at most, but if you really want it, go for it.
