[1.3 Build Advice] - EB or BM for a MF'ing Summoner/Totem Witch?

Hi! I'm fairly new to the game, only been playing on and off for about a week now, and now that I've played around a bit with the game and have seen a bit of how it works, I want to try to make my first Magic Find toon. Looking around, I figure the safest MF'er I could probably make is a Summoner type ala-Necromancer from D2. Playing around with the tree, I've come up with this build as my final build for this toon: https://www.poebuilder.com/character/AAAAAgMAGyVLrukC34ptGdlba9t9GOyKLJzR_aeUuJPN-nyDES1eXacrNbkRUB1PakPAVAj0vOr6gCqY2QunCJAzpqyIQEVHMtH3wRpsna6j8lorwxNY5Wae-tIdFI9GY_165nGFwBpG17FC2rkulJeFNPchsPFsrJj315uhw21ca4RIh2UQWAFv4veLenF5FxwSadsLgh7B85Ugaxc=

This is what I have so far, but one thing still concerns me. While this ensures max survivability, I'm a bit concerned for dps. I feel like my minions won't be able to do much dps and I won't be able to help much due to all of my personal dps investment going to totem due to AB, and I'm a bit uncomfortable with how much investment it would take to reach Gravepact with the current build for more minion dmg. After considering my options, I've found that if I take 18 points out of the EB/ES/CI lines and go down towards BM, I could easily pick up Ironwood for a bit of a dps boost and save a few points. My concern though, is that I'll basically kill myself casting spells while on harder hitting mobs/bosses that will probably plow through my undead army. I wanted to feel out the more experienced players who have done similar builds out. Is BM the way to go here for more dps, or EB for less dmg but more survivability?
