Confused by Mr Robot and Sim, Would love some ideas

So, current Resto build doing great in Raid. However, when checking spec in Mr. Robot it says best build uses less crit, less mastery, less haste, more versatility, but then makes no recommendation for changing gems, enchants, etc. Wondering if I should leave build at 51 crit, 70 Mastery, 13 haste, and 8 versatiliy, or would replacing gems and enchants really help? Any thoughts appreciated.

For raid purpose if you arent having mana issues you can drop or stop chasing crit.

With 50% crit and 40% from tidal waves buff to Healing surge you are almost guaranteed a crit.

Haste until you are comfortable with casts. This will also depend on your talent and playstyle.

This leaves mastery and versatility.

Versatility will give you more throughput while mastery will help in those burst healing of low HP targets.

This late in the xpac and with avg ilvl versatility IMO is gonna be your go to.

Thanks. Mana hasn’t been to big of an issue unless there is half a raid wipe and we trying to finish boss with just one or two healers left. Trying to get the Crit/Vers gear from last few Nyth bosses, but as all say… the drop gods hate…(insert class here).
