I would go with the following as a titan.
+10 blessed exalted heavy
blessed exalted weapon with the augument and Minor Greed SA (7% crit dmg, 3% damage)
*** +7 Elmore Cloak is a MUST*** - it is 30+ bil right now
Rings are now highly overpriced so I would stick with the Ring of creation & blessed exalted ( 2x 15% crit dmg rings)
Earrings/neck, stick with the blessed exalted ones
Circlet: Blessed exalted one for now, do not try to make a +5 radiant, just straight up buy it
Belt: I would go for Chef Monkeys belt if you find it at 5-6.5 bil else, stick with the R99 PVE belt
Artiftacts: this will get very expensive very fast, fill the book to get the +6% damage & -7% dmg received.
Try and get a +7 talisman of protection
Things to avoid:
Do NOT open event boxes !!
Do not buy a cheap +12 R99 weapon
Important things:
P Atk is not that relevant anymore, it matters if you play eviscerator and titan with melee attacks BUT you should focus on + Element attack, +PvE dmg, +damage, +crit dmg, there are more than 1 multipliers so 10% patk is close to nothing, even 20% patk is not that good. In comparison, 20% patk is less than 3% damage. If you have a lot of element and pve items then the +20% p atk will matter as opposed to now.
Do NOT expect to level in areas around your level, unless you get some serious gear, you will have problems leveling in 105+ areas, you will most likely stay in Phantasmal until 108 at least (with your current gear).
PoM prophet is nice but it will slow you down a lot! make a domi to at least 105/90 and use him out of party, give him your +8 R99 set, use the 5% skill cooldown from the tank tree and add skill cooldown dualclass skill, this way you will have reuse to 5 mins and 17 secs in VoP.
You can level up your PoM prophet with your dual later on!
