The first thing I did the very first time I logged into Homecoming was recreate my Bots/FF mastermind. It was slow going at first, because it's a late bloomer. I got to level 15 before I stopped and asked myself: wait, should I start over with time?
So I put my Bots/FF toon on a back burner, and tried out Bots/Time. And so far I'm having a blast. I'm now level 28, which means I have all my bots (but not the final upgrade), and Farsight from the time pool. I have most of my slots filled with level 25 or 30 IOs. I respecced the minute I got Farsight so I could 6 slot it, and I've maxxed out recharge and defense. Maxxed out recharge gets it almost to perma status. I got hasten from the speed pool to seal the deal.
Honestly I was already pretty tough before I got Farsight, wit the tohit debuff from time's juncture, but now it's just silly. I'm definitely not missing Bots/FF now. I'm about as invulnerable, PLUS I have debuffs on top of that. At 32 I'll get my final robot upgrade, and then at level 44 I intend to get Power Boost from the Mace Mastery patron pool, which apparently boosts Farsight.
As for affording a bunch of IOs, just sell all your orange salvage on the market. There are cleverer ways to make money on the market, but selling orange salvage as it drops is dead simple and sufficient to make a few million by level 20 or so. The hardest part is really making enough money to afford the LISTING fee to sell your first orange salvage. Scrape that together however you can, and then list the orange salvage at the current market price, and it should sell pretty quick. Once you have a proper bank-roll, never let it dip below 100k or so, so you won't get stuck in a "can't afford listing fee" hole again.
Then craft IOs at any university. use the /ah command to open an auction house window right there at the invention workbench, so you can buy any recipes and salvage you need without having to move an inch. Don't forget you can buy basic non-set IO recipes from the workbench, if they aren't cheaply available on the market. If you're short on cash, level 25 IOs are basically "good enough". You can also buy respec recipes from the AH.
