Why would you use 2 kiels ? You need to have a maya purple on you at all times, Fsoldier maybe ? When you are using MAGIC ? As a magic stalker you're far less vurnerable with 3 headgear cards than a clown or any other class that does need to damage through physical hits and can be stoned. As said before, using the helm gives you more potential. Live with the downsides like all other jobs have to do when they use different hats to get their full potential.A 3 kiel spam on AD on a gtb user will do decent damage. This is the exact same thing creators have to live with as well, FCP and GR that is.
You dont have to switch stats every second, you can switch skills around or find a HYBRID build instead of fully focussing on magic and then find it weird people use gtb. Dex stalkers dont have that problem because they use their own skill three to the full potential. They will use that double strafe and combo it with a different skill. Going for the magic tour is YOUR decision it's not "Something you have to go through". By going magic you increase your damage output but you also increase the chance of being countered. To work around this you can try using acid demo or stave crasher OR use a hybrid build and be able to switch to bow to DS. (The dex will give you a lot of aspd when wearing the bow, needing less agi for aspd. high dex, high int , medium vit, low agi and you should be able to have a fine hybrid build.) Also considering your low HP and defence... Can I remind you that stalkers have higher HP than creators and quite some other classes ?
Last of all. Stalkers have just as much chance vs gtbers as all magic classes have (if not more). so personally I see no reason to buff up stalkers because of that. Hence my opinion. I'll leave this as my last post here cause we can probably argue on forever which doesn't really have any use :O,
