I took the leap and completely removed Stealth.

Roleplaying the crafty adventurer, who uses a mechanical bow but isn't really much of an archer (lifted from Varric a little), obviously there's much to dodge and run from in those ancient trapped ruins; but I couldn't find a reasonable explanation why an aging explorer could move gracefully in complete silence.
New additions is the new upgrade to Shadow Strike, which turns it into another "finisher" throwing knife (the only thing I would kind of call his specialty); as well as the "bowling ball" Elemental Mine, because it adds versatility and fits the bill also (you need explosives, and specific ones to remove potential magical barriers... right?).
It's also better now, because it seperates Kel and Sera, whom I gave Archery, Subterfuge, Tempest and the Poison-half of the Sabotage tree - the "stealthy sniper junkie".
