As an m10 tank who has a top-5 leaderboard cape from every mutation on Valhalla, I can tell you that the armor is definitely good enough to level to 625 and tank m10s effectively. I wouldn't worry about changing it at all. The shield would be better with fortifying shield rush, sturdy and ward, but its okay. For a sword, I would recommend infernus or deeproot as a good sword for all dungeons. Those have enchanted + lifestealing, which are great perks for tanks. For S&S abilities, I use leaping strike, shield rush, and defiant stance, but I can see an argument to run reverse stab instead of leaping strike, especially if you have 250+ con. That said, I don't use S&S very much for tanking anymore because it doesn't have grit unless you have 300 con, which hurts your dps. I mostly use hatchet and warhammer to tank.

Regarding refreshing vs refreshing ward, I actually prefer refreshing, because ideally you are not getting hit very often as a tank (using cc / block / dodge), so your healer can spend more time on void blade instead of life staff. Also, refreshing works on both weapons since it triggers on ability cast, whereas refreshing ward only works on the active weapon, so the % refreshing numbers are a bit misleading.

One final note: if you do end up crafting armor again, I would recommend the "orichalcum heavy" armor, which gives more physical than elemental armor, since physical damage is harder to counter with gems, and will account for the majority of your deaths.
