v34 works fine on my Pi2, i also reported it to susan on discord under #developers.
Only issue i faced (but this was with previous versions like 30 also the case):
Performance is a bit worse than for example in 5.27.2. But you can increase performance by overclocking the pi2, setting the video mode to 720p (by default it is 1080p on a 1080p tv) and disable decorations/bezels
garret here the link for the latest v34 for pi2, just give it a try and report your findings:
