For my physical crit based ranger using split arrow, frenzy, hatred + grace. The char is fully evasion based with onars/arcobatics, so I've got like 45% to evade attacks, 90% to evade ranged attacks and 30% to dodge which rolls separately. Combined with relatively decent hp (3.5k) and maxed resists you're actually extremely durable.

Big difference is heading into the shadow tree to get the % mana leech passives so you don't need to gear with mana leech, the shadow area also has some really nice things for bow users.

The Blood Dance - Path of Exile Wiki
Lets you be able to run blood rage full time and drop any sort of leech gems you might want to link up with split arrow/frenzy. With split shot you wanna use faster attacks/pierce/added fire damage and power charge on crit. Power charge on crit is pretty amazing when you have 4 power charges that stack up super easy with split shot its another 200% crit. So you'll have 7 frenzy 4 power charges + blood rage at all times.
