Only put 1 point in "greater vitality". Personally, I would only put 1 in Salve too and put points in "recovery" and "stupefy" Stupefy is probably one of the best masteries to have maxed out for "cheap" so you can punish opponents while they're stunned and chain stuns for champs like OG Hulk, Tech spidey, Herc etc. That extra time can be a game change in AW and/or arena (if you grind).
Just noted you have points in greater strength too - only put 1 there. Use those to max out your Stupefy and Recovery. Once you get to a point where you are willing to invest units into unlocking other masteries... you want to at least get 1 point into despair, deep wounds and assassin. Depending on the champs you use most, despair and/or deep wounds can take your champs to a whole new level. But for now, work on improving the cheaper masteries to round things out.
Here's what I'd recommend. As a non level 60 person, the sooner you can get there, the more mastery points you can unlock - so I'd also use the XP boost masteries...
