Worth it to equip and stop other playing other classes?

[Mr Killer]

I have a chosen marksman now and I love to play it to the point were I've come up with this idea of selling my infantry and ranger gear (not Pikeman or support gear tho so I can still have a kiting character and help the team with cades). I would like to know people's opnions on this idea of mine especially from people who have done it before and I would also like to know good gear suggestions for a chosen marksman (each item under 6 mill cost) other than the crossbow and bolts which I've already decided on if I go through with this plan. It's also been bothering me to maybe wait and see for what new items will come out in the new item patch instead.

I have about an 11 Mill budget by the way

What Gear I Have Currently

Crossbowman:
Heavy Kettle Helmet
Emblemed Crossbowmans Mail
Plate Mittens
Plated Boots
Siege Crossbow (borrowing an arbalest)
Unscratchable Gold Bolts
Ornate Espada

Stuff I Would Sell

Transitional Armor
Defender Gauntlets
Head Crusher
Aegis Shield
Heavy War Hammer
Sharpshooter Bow
War Arrows
