Recommended maps to shape?

T1: Jungle / Arcade
T2: beach
T3: ?
T4: ?
T5: Mesa / Dunes (Dunes has burrowers...)
T6: Strand?
T7: ?
T8-10: Shape the worst maps in terms of xp/hour to get them out of the 'common map-drop-pool'

My personal recommendations of what I've enjoyed having shaped or plan to shape:

T2: Oasis
T3: Vaal Pyramid, Arid Lake
T4: Phantasmagoria, Acid Lakes
T5: Primordial Pool, Peninsula
T6: Strand, Wharf
T7: Castle Ruins, Cells

T8-T10: You still want to bump a couple good layouts to Reds
T8: Atoll
T9: Reef, Temple
T10: Courtyard

Note that it is easier to stay in red tier maps once you've completed a majority of the maps; therefore, you don't want to just bump bad layouts up to red level. I've been regularly hanging between T11 and T14 since I got >70/125.

I'm at 96/125 and red maps are still not sustainable for me. Even with 140+iiq and 30-43 packsize. They just bring me down to T10 again.

I see that many people like Cells. Cells used to have a lot of XP and you can shoot through the bars and by hugging the outer wall it can be cleared relatively fast. But I'm totem and I'm, not too sure about that one. Castle Ruins is indeed a nice alternative.

I'll wait a bit before shaping my higher tier maps for now. Just to see how it works out for other people I guess.

Beach. I would make it t12 if I could.

You might want to shape yellow maps that have the new base items, so you can get a better base for crafting (or a chance at better rare drops).

You have to check the individual pages for it atm.

My choices so far:

T1: Jungle Valley
T2: I picked Oasis, Beach is nice but seemed a bit too short (?)
T3: Arid Lake
T4: Phantasmagoria I think this goes without question
T5: Dunes
T6: Strand - it's Strand man
T7: went with Arachnid Tomb
T8: Atoll, another god tier layout
T9: Promenade and Coves
