This is wrong. You completely forgot about the instant heal, which also counts to the ticks so what you see (16%) is with 3k haste. For 13k haste, you need to add another tick at 1.42x which gives you +20%.

The 4pT15 is really that strong. Also, during BL it increases Rejuv by 24%. SotF Rejuvs are increased by 45%, SotF under BL by 55% (final critical ticks can do over 200k healing in that scenario).
I'm not saying you should never switch to T16, but people are really underestimating the value of T15. It's very very strong.

Also some other things: talking about best in slot means you have to look at the heroic item not LFR, so the stat increase is 8.51285%. Also in best in slot gear, you have a lot more secondary stats than in your calculation (I already have 5k more than you at 558, and I'm far away from best in slot).
